Version V2

The Northern California Community Study investigated the effects of urbanism on social networks and social attitudes. To do so, the study explored the relationship between characteristics and perceptions of neighborhoods, and the acquaintance patterns, social activities, and psychological attitudes of residents of particular neighborhoods in the San Francisco area in 1977. The study focused on the nonminority population. Part 1 (Respondent File) includes information obtained in personal interviews with 1,050 persons living in 50 communities in northern California. Included in this file are two general categories of variables--those describing the respondents' experiences in their neighborhoods and locales, and those recording the respondents' psychological states and feelings of well-being. Part 2 (Name File) contains information about 19,417 persons identified by the survey respondents in Part 1 as being part of their (respondents') social networks. Variables include whether the named individuals lived in the respondents' neighborhoods, and the types of relationships, interactions, and things in common that the respondents had with the individuals they named. Part 3 (Community File) contains a data record prepared for each tract of the sampling frame. The data in the Community file are summary counts for each tract's total population, total household population, total housing units, and selected demographic information, such as the percentage of Black population, percent residing in group quarters, and mean family income. The file also contains opinions gathered from the survey respondents about each community, e.g., ratings of local services, fear of crime, and the effect of the water shortage.

ICPSR cannot confirm the integrity of dataset 3, Community File, and will not include updated documentation, statistical program setup or system files, or the ASCII data file.

This collection has been updated to represent ICPSR's current standards. ICPSR and original documentation, SAS, SPSS, and Stata setup files, SAS transport (CPORT) file, SPSS system file, Stata system file, and tab-delimited ASCII data file are included.

The Name file (dataset 2) contains identification variables, CASEID and RESPID, with non-unique numbers for several cases. ICPSR created a unique sequential record identifier variable named ICPSRID for use with analysis.

Disproportionately stratified, multi-stage cluster sampling.

Household residents, aged 18 and older, living in urban areas of a circular quadrant of northern California extending approximately 200 miles east and north of San Francisco. Persons residing on military bases or in predominantly minority communities or meeting other specified criteria were not included.

1984-03-18 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Performed consistency checks.
  • Checked for undocumented or out-of-range codes.


  • Data in this collection are available only to users at ICPSR member institutions.
