Early in 2008, a number of organizations and individuals interested in accurate statistics on pet population numbers and trends gathered in a hotel in Houston, TX to review the available data on estimated pet populations and shelter demographics. While the data and analysis below was produced and subsequently added to by just one of those individuals, the following document takes into account the input from those who attended. For example, it was generally accepted that the AVMA pet population estimates from their quinquennial surveys are likely to be more reliable than the biennial surveys used to produce the APPMA demographic reports. [In the following report, all references to the AVMA surveys are to the quinquennial surveys by the American Veterinary Medical Association starting in 1981. APPA data refers to the surveys by the American Pet Products Association produced every two years since 1988.]
