In terms of ancestry, 11.3% were of German, 10.3% were of Irish, 6.3% were of English, 5.4% were of American, 1.5% were of Dutch, 1.5% were of Polish.
There were 3,261 households, of which 40.9 had children under the age of 18, 64 percent were married couples living together, 7.9 percent had a female householder with no husband present, and 23.7 percent were non-families. Of unmarried partner households, 89.5 percent were heterosexual, 6.3 percent were same-sex male, and 4.2 percent were same-sex female.
Twenty-one percent of all households were made up of individuals and 9.30 percent had someone living alone who was 65 years of age or older. The average household size was 2.74 and the average family size was 3.18.
In the county, the population was spread out with 30.6 percent under the age of 18, 8.4 percent from 18 to 24, 28.7 percent from 25 to 44, 20.7 percent from 45 to 64, and 11.7 percent who were 65 years of age or older. The median age was 34 years. For every 100 females there were 99.8 males. For every 100 females age 18 and over, there were 96.9 males.
The median income for a household in the county was $38,013, and the median income for a family was $45,565. Males had a median income of $31,558 versus $19,890 for females, indicating a relatively high level of income inequality based on gender. The per capita income for the county was $16,707.

Since the 1950s, Ochiltree has been an overwhelmingly Republican county. The last Democrat to carry the county has been Harry S. Truman in 1948, and although Truman won 73.06 percent of the county's vote, this is more than twice the proportion any Democratic candidate has won in the subsequent seventeen presidential elections – even Texan Lyndon Johnson did not reach 35 percent in his 1964 landslide, when Ochiltree was easily Goldwater’s strongest Texas county. Indeed, Jimmy Carter in 1976 was the last Democrat to win twenty percent of the county’s vote, and the last to reach so much as ten percent was Bill Clinton in 1996.
In 2004, Ochiltree County 91.5 percent of voters (2,922) voted for George W. Bush, while 8 percent (251 people) voted for John Kerry. Two people (0 percent) voted for Michael Badnarik ( Libertarian). This is tied for the second-highest percentage of votes Bush received for any county in the US (in both 2000 and 2004), and it is the highest percentage during the 2004 election, (only Glasscock County, Texas, at 93.1 percent, had a higher percentage in the 2000 Presidential election, though in both instances the percentages are skewed by the very small number of voters).
In 2008, 91.7% of voters supported Senator John McCain, whereas only 7.8% of voters supported Senator Barack Obama. Presidential elections indicate a strong sense of support for the Republican party.  It lost the title of most Republican county in the United States to King County, Texas.
Of the population aged 25 and older (5,441 people), 14.6 percent did not have a high school diploma, while the 12.9 statewide are without a high school diploma. Twenty-seven percent of the county claimed that a high school diploma was their highest level of educational attainment, compared with 24.8 percent statewide; 16.1 percent had a bachelor's degree or higher, compared with 23.2 percent statewide.
