Purpose and key findings Purpose Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 gives an overview of commuting patterns in the Auckland region using census data. For more detailed analysis of transport patterns in Auckland see Journey to work patterns in the Auckland region, commissioned by the Ministry of Transport and published in 2014. Key findings  In 2013, around a third of all employed people in New Zealand (596,313 people) gave a workplace address in the Auckland region.  There were 2.3 times more people who gave a workplace address in Auckland compared with New Zealand’s second largest labour market, the Canterbury region (255,480 people gave a workplace address there).  Waitematā local board had the highest number of people that gave a workplace address there. In 2006 and 2013, over 100,000 people living in the Auckland region (around 22 percent of employed people in Auckland) gave a workplace address in the Waitematā local board area.  Puketatapa, Waitakere Ranges and Manurewa local boards had the lowest percentages of people living and working within the same local board area.  In Auckland, 50 percent of employed people worked in an area that comprised of just 2.7 percent of the total land area in Auckland.  Auckland Central West area unit has the largest number (27,234) of employed people.  Auckland Central East area unit had the second-largest number (21,711) of people who gave a workplace address there but had the highest workplace density – 23,454 employed people per square kilometre compared with 23,343 per square kilometre for Auckland Central West.  Car transport was the dominant mode of commuting in Auckland, although car use has decreased slightly since 2001 – from 85.6 percent of employed people that went to work on census day in 2001 to 82.7 percent in 2013.  1 in 5 people that commuted to Waitematā used public transport. This proportion increased to over 1 in 4 for workers in the central business district (CBD). The Ministry of Transport defines the central business district (CBD) as the area units of Auckland Central East and West, Auckland Harbourside, Newton, and Grafton West. 6 2. Introduction Auckland’s local board areas Before 2010, Auckland was made up of seven territorial authorities: North Shore, Auckland, Waitakere and Manukau cities and Rodney, Papakura, and Franklin districts as well as the Auckland Regional Council. On 1 November 2010, the regional council, cities, and districts amalgamated and Auckland Council became a unitary authority. The Auckland region is made up of 21 local board areas, from Rodney at the northern end to Franklin at the southern end, as shown in figure 1. Data from the census has been back-cast so that a comparable time series can be produced. Therefore, even though the local boards have only been operational since 2010, we have included time series data for the boards. 7 Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 Figure 1 1. Population of Auckland local board areas, 2013 Census Population of Auckland local board areas, 2013 Census The Auckland region accounts for just over a third of New Zealand’s gross domestic product Auckland region has the only urban centre in New Zealand that consists of more than a million people. In the Auckland region, more than 9 out of 10 people (1,308,825 people) lived in the urban area of Auckland. Urban areas are statistically defined areas and are designed to identify concentrated urban settlements, without the distortion of administrative boundaries. The urban area of Auckland comprises the Northern Auckland 8 Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 Zone, Western Auckland Zone, Central Auckland Zone and Southern Auckland Zone (see figure 11). In 2013, there were 1,415,550 people usually resident within the Auckland region, which was 2.6 times the population of the next largest region, Canterbury (539,436 people). Economically, the Auckland region is a large part of New Zealand’s economy. Regional gross domestic product (GDP) estimates (Statistics NZ, 2013) showed that for the year ended 2013, Auckland contributed the most to New Zealand’s GDP (35.3 percent), followed by Wellington (13.5 percent), and Canterbury (13.2 percent). However, while Auckland has the largest economy overall, it does not have the largest GDP per capita. Taranaki had the highest GDP per capita ($74,341), followed by Wellington ($57,941), and Southland ($52,701). Figure 2 2. Gross domestic product and gross domestic product per capita by region Auckland’s share of the country’s GDP has remained relatively constant in recent years, although it fell slightly after the global financial crisis (from 35.9 percent of New Zealand’s GDP in 2007 to 34.7 percent in 2009). Previously, experimental estimates of regional GDP (Statistics New Zealand, 2006) calculated that in 2003, Auckland’s share of the country’s GDP was 36 percent and constituted almost half (46 percent) of the North Island’s GDP. Auckland’s population increased rapidly over the 20th century At the beginning of the 20th century the main cities of Auckland, Wellington, and Christchurch were fairly similar in population. However, throughout the 20th century and early 21st century, the Auckland metropolis grew at a higher rate than the next largest cities in New Zealand (Wellington and Christchurch), as figure 3 shows. 9 Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 Figure 3 3. Population of main urban areas, selected censuses 1886 to 2013 The population in Auckland’s urban area has increased relative to the next largest urban areas of Wellington and Christchurch. In 1991, Auckland’s urban area housed 2.9 times the population of Christchurch’s urban area, but by 2013 it housed 3.7 times the population of Christchurch’s urban area. The neighbouring urban areas of Hamilton and Tauranga have also grown rapidly in recent years. The geographic location of the Auckland urban area means that it has access to large populations north and south. Over the 20th and 21st centuries, growth in and around the Auckland metropolis has also been dispersed with a high dependence on private transport leading to a “scattered and decentralised settlement pattern” (McKinnon, 1987). In the mid-20th century, central and local government policy supported this decentralisation in Auckland, which resulted in a vast motorway system and a steady decline in public transport usage. Decentralisation has added costs. In a recent report Big city life? Challenges and trade-offs for Auckland city, the NZIER (2012) noted that better transport infrastructure would reduce costs for households. They calculated that each kilometre away from the city centre increases the cost of each commute by $738 per year. Recent changes as a result of local government policy and investment have improved the public transportation system and reversed the decline in public transport usage as chapter 4 shows. The Auckland Plan (Auckland Council, 2013) aims to promote housing along transport routes and consolidate growth within the existing metropolitan area. 10 3. Working in Auckland Around a third of all people in New Zealand gave a workplace address in the Auckland region Because of its sheer size and economic importance the Auckland region attracts workers. By 2013, a total of 596,313 people gave a workplace address in the Auckland region, compared with 544,017 people in 2006. Auckland has the largest labour market within New Zealand and is 2.3 times larger than New Zealand’s second-largest labour market, the Canterbury region (255,480 employed people). Auckland also attracts workers from surrounding areas, with 4,827 people from Waikato district and 1,530 people from Hamilton city giving a workplace address within the Auckland region. There are also people in other areas further afield, such as Dunedin (699 people), Kaipara (561 people) and Whangarei (516 people) that gave a workplace address in Auckland. However, we do not know whether these are people who share their time between two places (for example, people living and working in Auckland during the week) or whether the numbers have been inflated by incorrect workplace coding to a head office in Auckland. This situation can occur when a respondent does not supply sufficient information for their workplace to be coded correctly. The number of employed people that gave a workplace address in Auckland increased markedly in the 2000s compared with the 1990s. Between 1996 and 2001 the number of employed people that gave a workplace in Auckland increased by 5.5 percent. This was also a period of slow population growth. In contrast, between 2001 and 2006 the number of employed people that gave a workplace address in the Auckland region increased by 16.1 percent. Growth was again slower in the seven years between 2006 and 2013, at 9.6 percent, but was faster than population growth. In contrast, between 2006 and 2013 the population of Auckland rose by 8.5 percent. Figure 4 shows the change in the number of people giving a workplace address in Auckland and other selected regions between 1996 and 2013. Figure 4 4. Number of employed people that gave a workplace address by selected region 11 Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 Waitematā local board has highest number of workers in Auckland In 2006 and 2013, over 100,000 people living in Auckland (around 22 percent of employed people in Auckland) gave a workplace address in Waitematā local board area. This figure excludes people whose address could not be coded to a small area level. Table 1 1.

Source: Statistics New Zealand 12 Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 Commuting patterns by Auckland local board area This section looks at commuting patterns by Auckland local board area. Puketāpapa and Waitakere Ranges had the lowest proportion of people that lived and worked in the same area Figure 5 shows the proportion of people that lived and worked in the same local board area (referred to as self-containment). Great Barrier and Waiheke Island had the highest proportion of employed people that lived and worked in the same area. Figure 5 5. Percent of employed people living and working in the same area, by Auckland local board area The graphs and tables in this section show commuting between local board areas. Because of the sheer number of local boards, we have adapted the Ministry of Transport (Richard Paling Consulting, 2014) designation of local boards as inner urban, outer urban, and rural to visualise commuting between areas. In the following graphs we have included Waitematā separately for this analysis but have looked at their designation of the CBD separately when we consider the distribution of workplace address by area unit. Note that the Ministry of Transport has grouped Rodney, Waitākere Ranges and Franklin local boards as rural because they sit outside the Auckland metropolis. They excluded Waiheke and Great Barrier Islands. See Appendix 2. Commuting by inner urban boards Figure 6 shows commuting patterns by the inner urban boards. Here we see that most people in these areas live and work in inner urban boards. People tend to be concentrated within certain geographic locations – for example, over half of people in 13 Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 Kaipātiki work in inner urban boards north of the harbour bridge, while around half of employed people in Maungakiekie-Tāmaki worked in the southern part of the city. Figure 6 6. Usual residence by commuting destination for Auckland inner urban boards As previously stated, Waitematā was the largest employment centre in Auckland. People also travelled greater distances to work in Waitematā, which attracted workers from all round the Auckland region and outside the region as well. Just over 300 people in Hamilton city and Waikato district had a workplace address in Waitematā. Figure 7 shows the percentage of employed people in each local board that gave a workplace address in Waitematā. Note that these percentages only include those workplace addresses that could be coded to a small area level. 14 Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 Figure 7 7. Percent of employed population that gave a workplace address in Waitematā Around two-thirds of people that lived in Waitematā also worked there, a level of selfcontainment that was only surpassed by Great Barrier and Waiheke Island local boards. Around 4 out of 10 people that specified a workplace address in Auckland worked in the central locations of Waitematā, Albert-Eden, or Maungakiekie-Tāmaki. Commuting patterns for outer urban boards Figure 8 shows again the split between north and south for people commuting within and between local board areas. Few people commuted from northern outer urban areas to southern outer urban areas and vice versa. Around two-thirds of employed people in Howick, for example, gave a workplace address in either Howick or surrounding urban boards. 15 Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 Figure 8 8. Usual residence by commuting destination for Auckland outer urban boards Commuting patterns for rural local board areas in Auckland Figure 9 looks at commuting for the three rural local board areas, Rodney to the north, Waitākere Ranges (west), and Franklin (the southernmost area). Not surprisingly, the north/south split is very evident here with very few people in Rodney working in outer urban areas in the south and west. Franklin and Rodney have reasonably high proportions of self-containment with around half working in their own areas (here shown as the rural category). 16 Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 Figure 9 9. Usual residence by commuting destination, for Auckland rural boards. Usual residence by commuting destination for Auckland rural boards Urban/rural commuting to Auckland local board areas This section looks at numbers of people commuting by selected urban areas, and rural areas, to local boards within Auckland. Note that figures for rural areas include small numbers of people living in rural areas outside the Auckland region. Almost two-thirds of all commuting destinations within Auckland urban areas were to inner urban boards (here we are including Waitematā). This figure also includes people working from home. Some small changes occurred in the distribution of workplace addresses between 2006 and 2013 – although some caution must be used as changes in data over this time period may be partly due to changes in collection and processing of data. Within the Auckland urban area, the proportion of people giving a workplace address in an inner urban board (including Waitematā) fell slightly (from 60.9 to 59.5 percent of all workplace addresses).The number of workplace addresses in rural boards increased over this time but remained a fairly small proportion of the total. Figure 10 shows the distribution of workplace address for urban and rural areas within Auckland region. 17 Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 Figure 10 10.

Location of urban areas in the Auckland region Location of urban areas in the Auckland region, 2013 Numbers commuting to Auckland urban boards have increased between 2006 and 2013. In Pukekohe and Hamilton urban areas over 1,000 more people gave a workplace address in an Auckland urban board (including inner and outer urban boards) in 2013 compared with 2006. 19 Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 Table 2 2.

Symbols: C confidential .. not available Source: Statistics New Zealand Over 27,000 people worked in Auckland Central West Not all workplace addresses had enough information to be coded to area unit level in Auckland. Note that the numbers and proportions in the following section are calculated from the total stated workplace addresses that could be coded at area unit level. In total, 567,822 workplace addresses were coded to an area unit in Auckland. The numbers show us that employment is concentrated within the urban centre, but to a lesser extent than in the Wellington region. In Auckland, 50 percent of employed people worked in an area that comprised of just 2.7 percent of the total land area in Auckland. In contrast, 50 percent of employed people in the Wellington region worked in just 0.3 percent of the land area in the region. 20 Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 Figure 12 12. Employment density (workplace addresses per square kilometre) for Auckland, 2013 Census Employment density (workplace addresses per square kilometre) for Auckland 2013 Census Figure 12 shows employment density by area unit in Auckland. Auckland Central West (area unit) has the largest number (27,234) of people giving a workplace address there. Auckland Central East (area unit) had the second-largest number (21,711) of workplace addresses but a higher workplace density of 23,454 employed people per square 21 Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 kilometre compared with 23,343 per square kilometre for Auckland Central West. The Ministry of Transport defines the central business district (CBD) as the area units of Auckland Central East and West, Auckland Harbourside, Newton, and Grafton West. In total, 75,483 people had a workplace address coded to these area units. Figure 13 shows the area units with the largest number of workplace addresses and how numbers have changed over time. Auckland Harbourside shows the most dramatic change in numbers since 2001. Figure 13 13. Area units with largest number of people giving a workplace address Professional, scientific, and technical services dominate in the central city The most common industries for area units in the central business district were professional, scientific, and technical services (18,447 people) followed by financial and insurance services (13,161 people). In the largest employment centres to the south of the city, wholesale trade and manufacturing predominated. Table 3 shows the top industries of the area units with the largest employed populations. 22 Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 Table 3 3.

Commuting and modes of transport This chapter looks at how people got to work on census day. The data comes from the question about the respondent’s main means of travel to work. Main means of travel to work is the method a person aged 15 years and over used to travel the longest distance to their place of employment on census day (for example, by bicycle, bus, walking, or jogging). As this data relates to the main means of travel on census day, it does not necessarily indicate a person's usual mode of travel to work and it does not indicate the main means of travel to work for people who did not go to work on census day. Working at home Not all employed people are commuters. Around 10 percent of employed people in the Auckland region worked at home on census day. This proportion was much higher for people working in agriculture, forestry, or fishing (41.1 percent), rental, hiring, and real estate services (20.3 percent) and professional, scientific, and technical services (17.9 percent). Figure 14 maps the distribution of working at home by area unit and shows that working at home was more common on Great Barrier Island, and in Highbrook and Clevedon. 24 Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 Figure 14 14.

Car transport was the dominant mode of commuting in Auckland, although car use has decreased slightly since 2001 – from 85.6 percent of employed people that went to work on census day in 2001 to 82.7 percent in 2013. This percentage includes people who drove a private or company car, or who were passengers in a car. Figure 15 shows that the main means of travel to work has been relatively stable since 1996, although there have been increases in public transport use and active modes such as walking, jogging and cycling. Figure 15 15. Main means of travel to work for people that gave a workplace address in Auckland and travelled to work on census day Main means of travel to work by workplace address at local board level Table 4 shows the main means of travel to work by workplace address at local board level. Note that percentages have been calculated out of the total people who travelled to work on census day in 2013. Active modes of transport were more common in central Auckland and on the outlying islands. One in 4 people that worked on Great Barrier Island either biked, walked, or jogged to work. 26 Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 Table 4 4.

Note: All cells have been randomly rounded to base 3 Source: Statistics New Zealand 1 in 5 people that commuted to Waitematā used public transport People who commuted to work in the Waitematā local board area had lower rates of car travel. Waitematā also had a higher proportion of people using active modes of transport (walking or jogging and cycling) and public transport use. Just over 1 in 5 people who worked in Waitematā used public transport on census day, while just over 1 in 10 walked, jogged, or cycled. Figure 16 shows modes of transport for people that gave a workplace address in Waitematā, compared with percentages for total Auckland local boards. 27 Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 Figure 16 16. Main means of travel to work, for people that gave a workplace address in Waitematā and went to work on census day. Unlike Wellington, there were some workplace areas away from the city centre where high proportions of people commuted by bicycle. Whenuapai West had the highest proportion of people biking to work (8.0 percent of people that travelled to work on census day 2013). Public transport use was highest for those working in the CBD, with 18,279 people that worked there taking either a bus or train to work on census day, while a further 7,092 walked or jogged. The following maps show the mode of transport for travel to work by area unit of usual residence. The focus here is on numbers, rather than proportions, to give an idea of the actual numbers of people using different modes of travel on census day. As we can see active modes (walking or jogging and cycling) predominate for people living and working in the central city. Figure 17 shows the high proportion of people in central Auckland that used the active modes (biking, walking or jogging) to get to work. 28 Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 Figure 17 17.

While public transport is more dispersed throughout the city, again we see a concentration of use in the central city. 30 Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 Figure 18 18.

Note that train journey use is more concentrated for people in area units close to or adjacent with the train lines. Figure 19 19.

This category includes including taxi, ferry, helicopter, and aeroplane. However, In some areas such as Waiheke Island, a considerable proportion of the other category is likely to be people travelling by ferry. Figure 20 shows the number of people using an ‘other mode to get to work on census day. 33 Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 Figure 20 20.

As we would expect, this is more dispersed across the city, but tends to be higher on the outskirts of the central city and urban areas. 34 Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 Figure 21 21. Number of people who drove a private car, truck, or van to work by area unit of usual residence in Auckland region, 2013 Census Number of people who drove a private car, truck, or van to work by area unit of usual residence in Auckland region, 2013 Census 35 Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 Company car usage is more concentrated in certain areas with the highest concentration to the south of the central city. Figure 22 shows company car usage by workplace address so we can see the employment areas where company car use is concentrated. In Auckland, company car usage was highest among people working in construction (15,732 people), wholesale trade (9,885 people), and professional, scientific, and technical services (5,424 people). 36 Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 Figure 22 22.

Conclusion Auckland continues to dominate employment within New Zealand. In 2013, around a third of all employed people gave a workplace address in the Auckland region. Although the central city accounted for the greatest concentration of workers, Auckland has a more dispersed employment pattern than urban centres in the Wellington region. Car use continues to predominate in Auckland, although public transport use has increased since 2001. However, the location of the workplace has a real impact on commuting patterns with more people working in the city centre choosing public transport as a mode of travel. More than 1 in 4 people that worked in the CBD took public transport, compared with just under 1 in 12 people for the whole Auckland region. Train usage tends to be more concentrated in area units close to or adjacent with train lines. 38 References Auckland Council (2013). Proposed Auckland Unitary Plan.

See 2013 Census Information by variable for more detailed information. Usual residence Usual residence is the address of the dwelling where a person considers themselves to usually reside. It is recommended that these guidelines be followed in cases where usual residence is not self-defined.  Dependent children, who board elsewhere to attend primary or secondary school, and return to the home of their parent(s) or guardian(s) for the holidays, usually reside at the address of their parent(s) or guardian(s).  Tertiary students usually reside at the address where they live while studying. If they give up their usual residence in the holidays (e.g. terminate the lease on a flat or give up their hostel room) and return to the home of their parent(s)/guardian(s) during the holidays, their usual residence over that period would be the home of their parent(s)/guardian(s).  Children in shared care usually reside at the place where they spend more nights, or if they spend equal amounts of time at each residence, they usually reside at the place where they were on census night.  People who are in rest homes, hospitals, prisons, or other institutions usually reside where they consider themselves to live; this may include the institution.  A person whose home is on any boat, ship, or vessel permanently located in any harbour shall be deemed to usually reside at the wharf or landing place (or main wharf or landing place) of the harbour.  A person from another country who has lived the 12 months before 5 March 2013 in New Zealand, or has the intention of living in New Zealand for 12 months or more, usually resides at his or her address in New Zealand (as in external migration).  People who spend equal amounts of time residing at different addresses, and cannot decide which address is their usual residence, usually reside at the address they were at on census night.  If none of the above guidelines apply, the person usually resides at the address where they were on census night. Usual residence is self-defined. Workplace address Workplace address is the physical location of a workplace; distinguishing details can include the building name; street number, name and type; suburb or rural locality; and city, town, or district. The census data on workplace address relates to the workplace address for the main job held by an individual. This is the job in which a person worked the most hours. 40 Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 The data comes from Question 39 on the census individual form. Respondents such as milk vendors and sales representatives who have no fixed workplace are asked to state the address of the depot, headquarters, or reporting point from which they operate. Respondents who have no fixed workplace address at all are asked to respond that they have ‘no fixed workplace address’. The variable workplace address does not have a non-response category Respondents who were employed but did not state a workplace address were classified as 'New Zealand not further defined'. Respondents who stated a workplace address that could not be coded were also classified as 'New Zealand not further defined'. In 2013, 8.5 percent of responses were coded to the 'New Zealand not further defined' category. Respondents who state that they work across multiple areas (e.g. builders) are coded to 'No fixed address'. 0.4 percent of responses were coded to this category in 2013. Most of the problems with workplace address stemmed from coding issues. Sometimes these were caused by respondents supplying insufficient detail to workplace addresses to be coded. Where possible workplace addresses were coded using Statistics NZ's Business Frame. The issue with regional offices being coded to head offices was resolved for the majority of cases (as these occurred in Auckland, Wellington, and Christchurch) but there may be some cases when an apparent long-distance commute between other regional centres may be due to miscoding. This situation would have occurred in previous censuses. This data is broadly comparable with data from the 2006 and 2001 Censuses. Changes in the data over this time period may be partly due to changes in the collection, definition, or classification of the data rather than to real change. The Business Frame match rate for workplace address has increased from 60.2 percent in 2006 to 64.6 percent in 2013. This will improve the quality of both workplace address and industry/sector coding relative to 2006. An issue occurred in 2006 where usable responses were coded to 'New Zealand not further defined' instead of the correct meshblock, leading to a higher ‘New Zealand not further defined’ count. This has affected the comparability of the data over time. In 2001, 12.5 percent of the subject population was coded to 'New Zealand not further defined', compared with 14.5 percent in 2006. Due to better coding in 2013 only 8.5 percent of responses were coded to 'New Zealand not further defined' in 2013. Main means of travel to work Main means of travel to work is the method a person aged 15 years and over used to travel the longest distance to their place of employment on census day (for example, by bicycle, bus, walking, or jogging). As this data relates to the main means of travel on census day, it does not necessarily indicate a person's usual mode of travel to work and it does not indicate the main means of travel to work for people who did not go to work on census day. In 2013, 10.8 percent of those who answered the question indicated that they did not go to work on census day, compared with 10.8 percent in 2006 and 11.7 percent in 2001. Data is for New Zealand resident adults employed full or part time. Note that inconsistencies can occur when comparing 'Worked at home' counts from travel to work 41 Commuting patterns in Auckland: Trends from the Census of Population and Dwellings 2006–13 variable with 'Work at home' for workplace address indicator variable, due to differences in the reference period. Comparing this data with previous census data This data is fully comparable with the 2006 Census data. Changes in the data over this time period can be interpreted as real changes because there have been no changes in the way the data has been collected, defined, and classified. This data is highly comparable with the 2001 Census data. Changes in the data over this time period can generally be interpreted as real changes. There may be a small component of change over time that is due to minor changes in the collection, definition, or classification of the data. Since 2001 there has been a minor change in the question and a change in the treatment of multiple responses. In 2001 the motorbike category was worded 'Motorbike or power cycle', but for 2006 and 2013 this category was just 'Motorbike', and power cycles were not mentioned. In 2001 the first box marked was coded when a multiple response was given, whereas in 2006 and 2013 true multiple responses were coded to 'Response unidentifiable'. These changes have had little effect on the data because power cycles are a rare form of transport and the number of multiple responses to this question is very low. See the 2013 Census dwelling and individual forms. 42 Appendix 2: Adaptation of Ministry of Transport designation of inner and outer boards Table 5 5.
