Current Local Economics

Industry & Occupation

From 2008 to 2015 there were more than 74,000 jobs added to the civilian labor force here, a 20% increase that outpaced the county's population growth for the same period. The county's unemployment rate averaged 3.5 percent, January through November 2016, consistently a full point lower than the state or national averages, according to the Texas Workforce Commission. More current rates are available from the BLS or the TWC.

The  U.S. Census Bureau's American Community Survey (ACS) for Collin County also shows:

  • For the labor force in 2016 (more than 506,000, a.k.a. the 16 and older crowd):
    • Education services, healthcare and social assistance industries employed almost 20 percent;
    • Professional, scientific, and administrative and waste management services industries made up 16.4 percent;
    • Of the employed population, 84 percent were private wage and salary workers; 10 percent were government workers, and 5.8 percent self-employed.
​Workforce Education

The education level of the county's workforce just about doubles state and U.S. averages for degreed workers:

  • 49.7 percent of those 25 and older had a bachelor's degree or higher, far outpacing the state and national figure that hover between 26 and 28 percent.
  • More than 9 out of 10 workers 25 and older have at least a high school diploma.

Getting to Work

The ACS determined that the average commute to work for a Collin County resident is 28.2​​ minutes. For those less fortunate with their daily commutes, especially those heading to downtown Dallas at the crack of dawn, voters here passed a $235.6 million bond package in November 2007 to widen and improve our roadways, plus regional transportation funds from the Sam Rayburn Tollway generated another $900 million. For plans far in the future, take a look at Collin County's Outer Loop Project.

Meanwhile, the ACS figures go on to point out that:

  • More than eight out of 10 of county residents drive alone to work, which is higher than state or U.S. percentages;
  • Collin County residents work at home (7.4%) at a much higher rate than the state average; and,
  • County residents' mean morning work commute travel time shrunk by a fraction from 2000-2012, but remained a few minutes longer than national or state averages

Paychecks & Such

Collin County residents' paychecks also compare favorably to the rest of the country:
  • County residents' 2017 annual per capita income ($41,609) is more than 25 percent higher than the national rate;
  • Our median family income here in 2017 ($105,954) is about 33 percent higher than the U.S. median;
  • The 2017 county median household income was estimated at $90,124;
  • Less than one percent of county householdss were estimated to have received public cash assistance in 2017; and,
  • An estimated 6.9 percent of individuals here were living below the Federal Poverty Level in 2017. 

Housing and Households

Collin County had a 94-percent occupancy rate for the 320,000-plus housing units here:

  • Two-thirds of occupied housing are owner-occupied, with 32 percent rented out;
  • Traditional married-couple families make up 60 percent of total households;
  • The median monthly housing cost for an owner with a mortgage is $1,884 ($725 for owners without a mortgage) and $1,119 a month for the median rent; and,
  • Two thirds of these homes - about 117,000 - were built in 2000 or later

For a comparison between these and local figures on home values, please see the Certified Totals from the Collin Central Appraisal District.


Total school enrollment for ages 3 and up was estimated at 260,518 in 2017, which breaks down to 32,000 in pre-school and kindergarten, 173,000 in grades 1 through 12, and, more than 54,000 in college or graduate school. For individual school district enrollments please check our ISD links.

For an outside look at Collin County schools, Forbes Magazine ranked as 2nd in the natoin for its Best and Worst School Districts for the Buck. Additionally:

One of the biggest improvements to county public education came in early 2010, when Collin College’s Higher Education Center​, at Highway 121 (Rayburn Tollway) and U.S. 75 in McKinney. This new facility offers coursework for four-year degrees and graduate programs (both masters and doctoral) to county residents for the first time.

Where You From, Son?

Just in case you were wondering, Native Texans have lost the upper hand, population-wise, in Collin County. We're not sure exactly when that happened (and we're still checking on that) but the survey put people born in the Lone Star State at 45 percent in 2006. But that's not all that's happening to the cultural make-up of the county:

  • One in five county residents are foreign born, compared to slightly more than 17 percent in 2006;
  • About four out of 10 of those foreign born are naturalized U.S. citizens; and, 
  • A language other than English is spoken in almost one in four homes here, representing almost 150,000 county residents.
