Johnson County, Kansas

Quick Facts

2015 Population: 566,814
Median Household Income: $76,113
Poverty Rate: 6.2%
Unemployment Rate: 3.3%

Key Findings

Johnson County has many strengths that are important to public health — a higher-than-average median household income, a high percentage of well-educated residents, low rates of poverty and unemployment, and a low ratio of residents to health care providers. However, like most of the nation, Johnson County is seeing most of its population growth among adults over age 45. The number of seniors (age 65 and up) has grown by more than 53 percent since 2000. Overall poverty rates are down, at 6.2 percent, but that equates to 34,556 people living in poverty and an additional 63,253 between 100 and 200 percent of the federal poverty level. Racial and ethnic diversity is increasing, with minorities making up 19 percent of the population in 2015, compared to 11 percent in 2000. These trends may place an additional strain on the health system in the coming years. Cancer and heart disease are the leading causes of death, but at rates well below those of the state. The percentage of low-birth weight babies increased in 2017 and the overall trend line is up, which may be a cause for concern.

Information presented in this county profile is the most currently available as of September 2017.
