South Dakota's median age in 2016 was 37.0, making it the 38th oldest of the 50 states. This compares to No. 1 Maine, at 44.6, and No. 50 Utah, at 30.8.
The percentage of South Dakota's population under age 18 has been steadily declining since at least 1990, when it was 28.5%, compared to 24.6% in 2016.
Between 2010 and 2016, South Dakota's population grew faster than the nation as a whole. South Dakota's growth rate of 6.3% compared to the national rate of 4.7%.
More than 147,000 South Dakotans were people of color in 2016. This accounts for 17.5% of the state's population and continues a trend of healthy annual increases since 1990, when 8.5% of South Dakotans were of color.

South Dakota’s population grew by 0.9 percent between July 2015 and July 2016, ranking the state 14th among the fastest growing states in the nation, according to recently released U.S. Census data. Lincoln County, part of the Sioux Falls metropolitan region, was the fastest growing county in the state, with a 3.1 percent increase, while Meade County, part of the Rapid City metropolitan region grew by 2.4 percent.
The populations of South Dakota’s metropolitan areas grew at over twice the rate of the state’s micropolitan areas—1.3 percent to 0.6 percent growth. The Sioux Falls and Rapid City metropolitan areas saw increased populations from 2015-2016. The Sioux Falls metro area grew by 1.5 percent while the Rapid City metro area grew by 1.1 percent. The Sioux City metropolitan area edged up slightly by 0.3 percent during the same time frame.
While the Rushmore State’s metropolitan areas saw an increase in population from 2015-2016, so did several outlying counties. Mellette County grew by 2.5 percent from 2015-2016, although its population decreased by 2.4 percent from 2014-2015. Lake County in eastern South Dakota also grew by 2.5 percent.
The Black Hills region grew by 1.0 percent during the same time period. While Meade County led the region at 2.4 percent, Custer and Lawrence County grew by 1.7 and 1.6 percent, respectively. Pennington County experienced the slowest growth in the region at 0.7 percent.
The population of the Spearfish micropolitan area expanded by 1.7 percent, faster than any other micropolitan area in the state.
The number of South Dakota residents over the age of 65 continues to increase, according to U.S. Census data. There were 134,420 seniors over the age of 65 in the Rushmore State in 2015, up from just 118,472 in 2011. Additionally, the population of seniors aged 85 and above increased from 19,766 in 2011 to 21,368 in 2015.
Potter County had the highest percentage of seniors at 28.8 percent, while Oglala Lakota County had the lowest at 6.8 percent. Minnehaha County had the most senior residents in the state with a population of 23,258. Buffalo County had the fewest residents aged 65 and older with a total population of just 161.
The Black Hills region has seen a substantial increase in the senior population since 2000. In 2015, 16.4 percent of the Rapid City metro area’s population was aged 65 or older, up from 14.6 percent in 2012, and 11.5 percent in 2000. The Spearfish micropolitan area’s senior population was 19.2 percent in 2015, up 4.6 percent from 2000. By comparison, the Sioux Falls metropolitan area has only experienced a 1.0 percent increase from 11.6 percent in 2000 to 12.6 percent in 2015.
The median household incomes of individual aged 65 and above also increased in 2015 to $37,896 from $35,285 in 2014. However, income gaps persisted. Men 65 years and older had a median household income of $52,200 in 2015, while women had an average of $27,400 during the same time period.
Poverty rates also declined for South Dakota seniors. In 2015, just 6.5 percent of seniors aged 65-74 lived below the federal poverty level compared to 8.9 percent in 2014. The poverty rate for seniors over the age of 75 also decreased in 2015 to 10.6 percent in 2015 from 12.7 percent in 2014.
The proportion of South Dakota's population age 65 and older has been growing steadily since 2011 while the population of 5-17 and 18-64 year-olds has stabilized. The 65+ population has increased by 13.46 percent since 2011, compared to a 2.12 percent rise in the 0-4 age group. See the table below for growth rates since 2011 for all age groups.
|Age Group||Growth from 2011-2015|
The population of residents age 65 and older has dramatically increased in the Black Hills region compared to the state as a whole. The Black Hills 65+ population has grown by 21.63 percent since 2011 compared to a 13.46 percent increase for this age group statewide.
The increase in residents age 65 and older has augmented the retirement-to working-age ratio statewide which has grown by 2.6 percent since 2011.
This trend follows projections by demographers who say that the United States population of 65+ individuals will dramatically increase within the next 50 years due to the aging of the baby boomer generation.

After ticking up a slight 8.2 percent between 1940 and 1990, South Dakota's population started climbing in 1990 and grew 23 percent by 2015. Between 2014 and 2015, however, population growth in the Rushmore state was 0.6 percent, the smallest percentage in the past five years.
Growth slowed to below 1 percent (0.95 percent) from 2013-2014 after annual growth was about 1.25 percent for each of the previous three years, according to federal data.
Here's a look at the state's population growth over the years:
|TOTAL SD POPULATION|
Just four states have smaller populations than South Dakota, which is one of five states with a population of less than 1 million. The other under-a-million states are Delaware (945,934), North Dakota (756,927), Alaska (738,432), Vermont (626,042) and Wyoming (586,107).
As South Dakota's population as a whole has grown, about 10,000 people emptied out of the countrysides between 2000 and 2015, while the metropolitan areas logged 31.5 percent population growth (98,402 people) from 312,495 to 410,897. South Dakota's metropolitan areas are those of Sioux Falls, Rapid City and one county within the Sioux City area.
The state's rural "non-metropolitan" areas had a population of 227,718 in 2000 and 217,909 in 2015, a drop of 4.3 percent. The rural parts of South Dakota experienced population loss every year up until the Great Recession hit. After 2009, South Dakota's rural population experienced minute annual growth except for 2010-2011, when it declined. From 2014-2015, rural South Dakota's population grew by 0.1 percent (222 people).
South Dakota's micropolitan areas grew by 7 percent. Combined, the communities of Aberdeen, Brookings, Huron, Mitchell, Pierre, Spearfish, Watertown, Yankton and Vermillion and their surroundings added 15,032 people.
Those population changes shifted South Dakota's population to be more urban. Here's a look at how the state's population shifted in the past 15 years.

The fourth installment of Trivia Tuesday is ready to enjoy. Impress your friends and coworkers after learning smart-sounding data from our sleek infographics. Further your education by scrolling to the end of the page and clicking the text links to dive deeper into the data at hand. This week’s installment focuses on women in South Dakota by the numbers.
The U.S. Census Bureau uses a set of dollar value thresholds that vary by family size and composition to determine who is in poverty. For example, for a family of two adults and two children interviewed in July 2014, the federal poverty threshold was about $23,818. The poverty threshold for a family of this size and composition will vary slightly depending on the month.
Both the number and percentage of South Dakota children living below poverty rose after the Great Recession in 2009, while at the same time the number and percentage living at below half the poverty threshold has dipped. The overall percentage of children living in poverty in the years leading up to the recession was about 16 percent, split about evenly between those living below 50 percent of poverty and those living between 50 and 99 percent of poverty.
Nearly every year since 2009, about 18 percent of South Dakota's children have lived in poverty. Of those, between 10 and 11 percent have lived between 50 and 99 percent of poverty and less than 8 percent have lived at below half of poverty. The 2014 rate of 7 percent (14,546 children) at below half of poverty marks a low in both percentage and total number since at least 2006.
At the same time, the 10.9 percent (22,581 children) living between 50 and 99 percent of poverty in 2014 marked the highest number since at least 2006 (though the increase is well within the margin of error) and tied with 2009 for the highest percentage in that time period.
Meanwhile, more children moved into higher income categories in 2014. Here's a look at other income strata for that year:

Since 2009, males have been the majority in South Dakota and they have been growing faster than females in recent years, according to recently updated federal data.
In 2000, women and girls outnumbered men and boys by 5,728 -- 380,286 females compared to 374,558 males. By 2014 that dynamic had reversed, with males outnumbering females by 5,451 -- 429,313 males compared to 423,862 females.
In 2009, males overtook females in the state, with 403,869 males compared to 403,198 females. Since then, males have made larger gains than females, growing 5.4 percent between 2010 and 2014 compared to 4.2 percent growth for the female population. Overall, South Dakota's population grew 4.8 percent during that time.
