Demographic-Economic Patterns: Composite & Related Geography

.. we often need data for study areas that do not conform to conventional political/statistical geography. The geography for a market, sales territory, impact zone or other type of study area often do not align with political or statistical geographic areas for which relevant demographic-economic data are available. While the interest might be in demographic-economic characteristics for a particular county, patterns and trends within a county cab vary widely for sub-county geography such as ZIP code areas, census tracts, cities, school districts and other types of geography. It is important to be able to examine the composite, or drill-down, geography for a larger area. Related geography are equally important. Even though primary interest might be in three ZIP code areas, knowing about patterns in related, contiguous ZIP codes is also important. This section illustrates how to examine semi-comprehensive demographic-economic characteristics and trends using organized profiles for alternative geography.
