Sample selection procedure for St. Joseph County, Indiana
St. Joseph County, Indiana, was under consideration as a possible second site for the Housing Assistance Supply Experiment. In light of that possibility, data on all real estate tax parcels in the county were gathered as a sampling frame from which a screener list of about 6,000 properties could be drawn for baseline surveys. Useful sources of the data included county real estate tax tapes, property records, city and county directories, water and electric company billing records, Area Plan Commission lists of large housing projects, and knowledgeable local officials. Stratification variables were defined for residential and nonresidential parcels. Fieldwork procedures were established, and a preliminary 13-week schedule for sample selection was drawn up pending final decision on the site selection.
