Harris County anchors the Texas Gulf Coast with a majority-minority electorate that has redrawn the state's competitive map — its 3.4 million residents make it the third-most-populous county in the nation.
The county's recent history is a story of close margins. The Democratic margin reached seventy-six points in 1936; the Republican margin reached twenty-six points in 1972. Most other elections have been decided by single-digit points.
Harris County's demographics — a population of 4,838,303, a 34% non-Hispanic-white share, a median household income of $74,983 — situate the county close to national averages on several dimensions. The county's voting pattern over the last decade is most similar to that of Loudoun County and Kane County.
