How is Demographics USA better than other directories?
We can’t speak for anyone else’s research, but we can tell you that our directories have an excellent reputation for accuracy and usefulness. Nielsen Claritas maintains and annually updates the most comprehensive database available with approximately 450 household variables at the ZIP Code, County, DMA® and MSA levels. For each geographic level, Nielsen Claritas updates households, total population, group quarters by age, sex, race and income. The latest population census serves as the benchmark for the Nielsen Claritas population updates. For the intercensal years, Nielsen Claritas employs a multitude of sources to update the database. Additionally, local area population estimates, postal deliveries and individual state department of health data are used to evaluate and adjust the estimates. State-of-the-art demographic techniques are used for the updates. Several indirect estimation procedures and modeling techniques are applied to overcome deficient data and enhance these estimates.
