A Query is used to select records based on specific criteria.
Queries can be very simple yet powerful. For instance, only records where the Average Income was greater than $50,000 can be selected quite easily. The EASI Query Basic can also be quite complex, such as finding areas where either the Average Income was greater than $50,000 or there were at least 1,000 households earning $200,000 and above. In a search for ethnic populations, areas could be located based on a query for anywhere the number of individuals who speak Spanish was at least 10% of the population of that area. The EASI Query Advanced customizes a query until the exact study group is identified.
