The second Housing Assistance Supply Experiment survey of neighborhoods was conducted in St. Joseph County, Indiana, from January 1978 to March 1979. The survey had two parts: compilation of neighborhood local sources (NLS), and observation of neighborhood street segments (NSOB). The NLS collected information on access to public facilities and services; characteristics of highways, arterials, and railroads; and statistics on schools and crime. The NSOB collected observation data on neighborhood characteristics such as types of land use; condition of residential buildings, landscaping, sidewalks, and streets; and overall cleanliness. The data from both surveys are generally complete and of good quality. Because of missing information, however, the data do not adequately represent three NLS variables: total church membership, average weekly church attendance, and crime. The NSOB's averages of neighborhood condition ratings are sufficiently varied and consistent to serve as useful analytical indexes of neighborhood quality.
