The following communities are census-designated places, meaning population and demographic data is available from the U.S. Census Bureau for each one: Historically Douglas was the most Republican county in Nevada, a state that tended to lean Democratic between the 1890s and 1950s.

It was the only Nevada county won by Charles Evans Hughes in 1916, and one of only two to vote for Progressive “Bull Moose” ex-President Theodore Roosevelt in 1912.

It was also one of only two Nevada counties that voted for incumbent President Benjamin Harrison over insurgent Populist James B. Weaver in 1892 when the latter carried the state by over 40 percentage points.

Even when the county did vote Democratic in 1896 and 1900, it was by much smaller margins than the rest of silver-mining Nevada.

Apart from FDR's two victories, only two Democrats since 1920 — Lyndon Johnson in 1964 and Barack Obama in 2008 — have won even 40 percent of the county's vote.

It serves all of Douglas County,[18] having two main areas: Lake Tahoe & the Carson Valley.
