The National Cycling Participation Survey (NCPS) is a standardised survey that has been repeated biennially since March/April 2011 , with minor changes to the survey structure between 2011 and 2013. The NCPS provides data on cycling participation at a national level and allows for estimates of participation for each state and territory, and the capital cities and non-capital areas within each state and territory. The primary survey objective is to obtain accurate data on cycling participation to monitor performance towards the National Cycling Strategy 2011 -16 target of doubling cycling participation. The objective is to measure participation rather than travel. Participation is defined as the number of individuals who have cycled for any journey or purpose and in any location over a specified time period. By comparison, travel is the number of cycling trips that occurred over that time period, and may include the distance travelled, purpose and so on. Participation is much easier to define, and for individuals to recall, than travel. It is reasonable to expect an individual would remember whether they had ridden a bicycle over the past week, month or year, but far less likely they would be able to accurately recall the number of trips they have made over that period. Further details on the method and results used in NCPS are reported in detail elsewhere 1. The survey is a telephone-based survey of residents of the study area, and includes coverage of mobile-only households 2. As cycling participation is greatest among children, it is critical that the survey have coverage of this group. Data on cycling participation of those aged under 15 is obtained by asking an adult in the household to report on behalf of other household members, including children. The survey fieldwork is undertaken by Market Solutions Pty Ltd and the data analysis and reporting is provided by CDM Research. The person-level data are weighted at the gender and age level (2 — 9, 10 — 24, 25 — 49, 50+) to the ABS census 2011 population. The household-level data are weighted to ABS census 2011 household size (1, 2, 3, 4, 5, 6+ usual residents). The number of persons cycling is estimated by expanding the 2011 weights to the estimated resident population for 30 June 2014 provided by the ABS. The estimates presented in this report are based on a sample of residents from Australia. These estimates are subject to sampling variability as only a proportion of residents (approximately 0.09% of the resident population) were interviewed. The approach adopted in this report to expressly this variability is to present the 95% confidence interval. This represents the range within which we would expect the true population estimate to reside 95% of the time. Significant differences between parameters are present where the point estimate falls outside the confidence interval. The sample consisted of 8,375 households containing 20,879 persons (Table 1 .1 ). The sample sizes in NSW were much larger than other locations as data from a separate survey instrument was used for metropolitan Sydney. In Queensland additional sampling was undertaken in metropolitan Brisbane at the request of the Brisbane City Council. The total sample sizes are similar to in 2011 and 2013, aside from the larger sample for Queensland. (Author/publisher)
