| MSA | See tab - Geographical Codes - Metropolitan Statistical Area (MSA) | A metropolitan statistical area (MSA), formerly known as a standard metropolitan statistical area (SMSA), is the formal definition of a region that consists of a city and surrounding communities that are linked by social and economic factors, as established by the U.S. Office of Management and Budget (OMB).

| CBSA | See tab - Geographical Codes - Core Based Statistical Areas (CBSA) | New metropolitan and micropolitan statistical area definitions were announced by OMB on June 6, 2003, based on application of the 2000 standards with Census 2000 data. Metropolitan and Micropolitan Statistical Areas are collectively referred to as Core-Based Statistical Areas. Metropolitan statistical areas have at least one urbanized area of 50,000 or more population, plus adjacent territory that has a high degree of social and economic integration with the core as measured by commuting ties. Micropolitan statistical areas are a new set of statistical areas that have at least one urban cluster of at least 10,000 but less than 50,000 population, plus adjacent territory that has a high degree of social and economic integration with the core as measured by commuting ties.

| CNTYSIZECD | County Size Code:A - Any county located in the 25 largest U.S. cities or their consolidated statistical urban areasB - Any county not designated as an A County that has population over 150,000 or is part of a consolidated statistical area with population over 150,000C - Any county or consolidated statistical area not designated as an A or B County that has population over 40,000D - Any county statistical area not designated as an A, B, or C County | A, B, C, and D counties are based on the population totals of U.S. counties and also their proximity to a metro area or anchor city. A counties are the largest U.S. counties by population, and D counties are the smallest. Counties are classified on the basis of data from the latest census, which takes place every 10 years. |
| LATITUDE | Up to 6 decimal precision for non-PII version and 6 decimal precision for PII version | The geometrical location north or south of the equator assigned to the address. A value in decimal degrees to an accuracy of 4 decimal places is accurate to 11.1 meters, a value of 6 decimal places is accurate 0.111 meters. |
| LONGITUDE | Up to 6 decimal precision for non-PII version and 6 decimal precision for PII version | The geometrical location east or west of a north-south line, called the prime meridian, assigned to the address. A value in decimal degrees to an accuracy of 4 decimal places is accurate to 11.1 meters, a value of 6 decimal places is accurate 0.111 meters. |
| GEOLEVEL | See tab - GeoLevel Precision Assignment | The level of precision at which the Latitude and Longitude are assigned |
