          <abstract>The RAND Center for Population Health and Health Disparities (CPHHD) Data Core Series is composed of a wide selection of analytical measures, encompassing a variety of domains, all derived from a number of disparate data sources. The CPHHD Data Core's central focus is on geographic measures for census tracts, counties, and Metropolitan Statistical Areas (MSAs) from two distinct geo-reference points, 1990 and 2000. In this collection, Street Connectivity, two datasets are available: one for the 1990 Census and another for the 2000 Census. These files contain one record per census tract and have several measures associated with the street network data based on the TIGER/Line files available for each Census. These measures have been computed using ArcGIS software. At the tract level, the type of measures included are: number of street segments and intersections, average and median block length and block size, ratios of the actual number of complete loops to the maximum number of possible loops given the number of intersections, and ratios of the actual number of street segments to the maximum possible given the number of intersections.</abstract>
 			
           <abstract>The purpose of the CPHHD Data Core Series is to provide projects with the data tools necessary to conduct quality, population-based, health-relevant research.</abstract>
