Unsurpassed methodology-For nearly 40 years, Nielsen has delivered annual demographic data updates. In building the demographic update, Nielsen relies on data obtained through federal government agencies such as the U.S. Census, U.S. Postal Service, the Federal Housing Finance Agency, local government agencies and non-governmental sources such as Equifax, Valassis, Hanley Wood, Ethnic Technologies (E-Tech) and the National Association of Realtors. This data is utilized in a combined ’bottom-up’ and ’top-down’ process for generating current year estimates and five-year projections for demographic base counts, population characteristics, household characteristics and housing unit characteristics.
In the "bottom-up" process, local level data is used to assess demographic growth and decline in small geographies. In the "top-down" process, U.S. Census Bureau estimates and other federal data are used to develop totals for demographic variables for larger areas such as cities, counties and states. These independently produced estimates serve the important function of methodological control–a checks and balances measure to ensure that any indications of demographic change are consistent across all demographic data sources.
