As of the 2000 United States Census,  there were 153,406 people, 58,212 households, and 43,484 families residing in the county. The population density was 181 people per square mile (70/km²).

As of 2005 Benton County's population was 81.7% non-Hispanic white, while the percentage of Latinos grew by 60 percent in the time period. Latinos are attracted to the growth of light industrial jobs, home construction and service sector in the county. 1.1% of the population was African-American (perhaps the lowest in all of Arkansas); 1.6% was Native American (the historical presence of the Cherokee Indians live in close proximity to Oklahoma); 1.7% was Asian (there was a large influx of Filipinos, Vietnamese and South Asian immigrants arrived in recent decades) and 0.2% of the population was Pacific Islander. 1.6% reported two or more races, usually not black-white due to a minuscule African-American population. And 12.8% was Latino, but the United States Hispanic Chamber of Commerce believed the official estimate is underreported and Latinos could well be 20 percent of the population. 
There were 58,212 households out of which 34.40% had children under the age of 18 living with them, 63.00% were married couples living together, 8.20% had a female householder with no husband present, and 25.30% were non-families. 21.10% of all households were made up of individuals and 8.50% had someone living alone who was 65 years of age or older.

The median age was 35 years. For every 100 females, there were 97.40 males. For every 100 females age 18 and over, there were 94.90 males.
The median income for a household in the county was $40,281, and the median income for a family was $45,235. Males had a median income of $30,327 versus $22,469 for females. The per capita income for the county was $19,377.

Politically, Benton County is arguably one of the most Republican-Leaning Counties in Arkansas. Benton County has not voted Democrat in a Presidential election since 1948 when a former senator from bordering Missouri, Harry S. Truman won Benton County along with winning Arkansas as a whole. 
- Walmart corporate headquarters is located in Bentonville.
- Daisy Outdoor Products, known for its air rifles, is headquartered in Rogers.

Like all of the conservative Bible Belt of the Ozarks and Ouachitas, Benton County is strongly Republican; however, it has been such for longer than most of the region. It voted Republican in 1928 and 1944, and the last Democratic presidential nominee to carry the county was Harry S. Truman in 1948,  and along with nearby Sebastian County it was one of the few counties in Arkansas to resist the appeal of southern “ favorite sons” George Wallace, Jimmy Carter and Bill Clinton.
Note: Most Arkansas counties have names for their townships. Benton County, however, has numbers instead of names.
Townships in Arkansas are the divisions of a county. Each township includes unincorporated areas; some may have incorporated cities or towns within part of their boundaries. Arkansas townships have limited purposes in modern times. However, the United States Census does list Arkansas population based on townships (sometimes referred to as "county subdivisions" or "minor civil divisions"). Townships are also of value for historical purposes in terms of genealogical research. Each town or city is within one or more townships in an Arkansas county based on census maps and publications. The townships of Benton County are listed below; listed in parentheses are the cities, towns, and/or census-designated places that are fully or partially inside the township.
