The region around the cities of Dallas and Fort Worth, frequently grouped together under the label of "the Dallas metro area," is a large metropolitan zone comprised of thirteen counties centered primarily around the city (and county) of Dallas. Other counties within the region include Collin, Denton, Ellis, and Parker counties. Put together, the counties within this metro zone have a population near 7.5 million. With some of Texas's most populous counties and bountiful opportunities for work, the Dallas metro increasingly attracts people who wish to live and work in the area.For employers in Dallas, the Dallas suburbs, or even in a county that borders the metro region, it is increasingly likely that the applicants with whom you interact have previously resided in one of these counties. For that reason, a vetting process that looks at the "big picture" and provides hiring managers with a complete snapshot of an individual's history is necessary. For a business based in Dallas county, for example, looking at only the records available within that county could miss the whole story.
