Many surveys conducted in the U.S. are not national in scope but instead are designed to represent residents of a single community, city, county, state, or region. These surveys tend to have similar sampling procedures to many national surveys, but the people sampled are limited to the geographic area of interest. For example, residents of states can be sampled using the random digit dialing procedures described for our national surveys. However, there may be some error with sampling cell phones in a particular geographic area as discussed in the section on sampling cell phones.

The Pew Research Center has conducted a number of state surveys, especially in the context of upcoming presidential primaries. And, we have conducted some special surveys of metropolitan area residents of Philadelphia, New York and Washington.
