Zhenzhong Wang / Abstract: Pet Demographics Survey (PDS) is a nationwide survey on pet ownership, veterinary visit and expenditure, which is conducted every five years. Metro Market Demand Survey (MMDS) is a smaller survey conducted every year. It is a supplemental survey for PDS and surveys about six geographic sub-regions of the U.S.. It has two goals: (1) Provide estimation of household pet ownership, veterinary visit and expenditure of each sub-region. (2) Annually update the nationwide PDS estimates by imputation. In this talk, I will firstly review the 2016 PDS (completed in 2017) and the sampling design of 2017 MMDS, and then talk about the estimation procedure for each sub-region based on MMDS survey. Finally I will discuss the imputation procedure for updating nationwide estimation of PDS in 2017 and show the results.
