*Figures are based on estimates. The survey changed from face-to-face to online in 2021, which means 2021 and 2022 data cannot be compared with earlier years but the percentage of households owning pets can be compared between 2022 and 2021 with some caution required as the sample size changed from 5,093 in 2021 to 8,983 in 2022. Sample sizes vary as follows: n (2019/20) = 8,000; n (2018/19) = 8,000; n (2017/18) = 8,000; n (2016/17) = 8,000; n (2015/16) = 8000; n (2014/15) = 8353; n (2013/14) = 6,192; n (2012/13) = 4,223; n (2011/12) = 4,205; n (2010/11) = 4,156.
The source did not publish 2025 pet population data due to anomalies that compromised the data.
