Texas Muslim Communities by County: The 2020 Religion Census

The 2020 U.S. Religion Census provides a common reference for comparing Muslim congregations and estimated adherents across Texas counties. In its Harris County report, the Muslim Estimate category records 63 congregations and 91,156 adherents. Dallas County records 38 congregations and 60,393 adherents. These figures belong to the study’s 2020 reporting framework; they are not a present-day count of every Muslim living in either county. [1] [2]

The selection below covers six counties associated with the Houston, Dallas–Fort Worth and Austin regions. It is not a ranking of all 254 Texas counties. Each row links to its original ARDA report. [1] [2] [3] [4] [5] [6]

What the columns mean

Congregations measure organizations or sites with regularly scheduled worship under the reporting body’s definitions. Adherents are a broader participation measure, generally including members, children and other associated participants. ARDA cautions that definitions vary among religious bodies. The last column expresses the reported estimate relative to the county population: 19.27 per 1,000 corresponds to approximately 1.93 percent, not 19.27 percent. [1] [7]

Comparing the first two numeric columns therefore answers different questions. A larger number of congregations does not automatically mean a larger estimated population, and neither column measures attendance at a particular Friday prayer. The figures are most useful when the question, unit and reference year stay attached to one another.

Reading beyond a county line

A county boundary is not a community boundary. The Houston and Dallas–Fort Worth guides organize institutions across their wider regions, whereas this table uses the county geography in the source. A reader researching Richardson, for example, should not substitute the Dallas County total for the entire North Texas community. Use the DFW guide for institutional context and the Houston guide for a different regional view.

For statewide estimates from other years, consult How many Muslims live in Texas?. The figures there and here should not be joined into a growth curve without checking their methods. This page’s contribution is a transparent selection and explanation of a published dataset—not a new survey or a forecast. Download the six rows: JSON. The same framework is applied at state level in the six-state comparison.
