Summary View help for Summary
This component of the Philadelphia Social History Project examines the demographic composition of city grid squares using census data from years 1850, 1860, 1870, and 1880. The collection consists of two types of data files: (1) grid tallies, and (2) grid dictionaries. The grid tally files consist of counts of individuals living in PSHP grid squares, with totals broken down by race/ethnicity, sex, and age. The grid dictionary files link lines in the census manuscripts to PSHP grid squares, allowing users to follow the movements of census-takers as they moved house-to-house on foot, adding individuals to the printed census manuscript forms. The "grid" network consists of a set of vertical and horizontal lines drawn at fixed intervals across a city map, forming the foundation for the spatial organization of the data. The grid dictionary files show when census-takers crossed from one grid square to another; each row in the grid dictionary describes a set of rows that are in a specific grid square by listing the starting page/line and the ending page/line.

Study Purpose View help for Study Purpose
The purpose of the grid data component of the Philadelphia Social History Project is to allow historic demographic researchers to analyze changes in the city's residential patterns; the data are especially useful for analyses of the evolving degree of residential integration versus segregation amongst various population subgroups.

2014-07-30 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:
- Created variable labels and/or value labels.
- Checked for undocumented or out-of-range codes.
Notes
The public-use data files in this collection are available for access by the general public. Access does not require affiliation with an ICPSR member institution.
