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 Indian reservation counties remain among the highest poverty rates for school-age children, according to new U.S. Census Bureau estimates released this month.
These counties encompass the Cheyenne River, Rosebud, Pine Ridge and Crow Creek reservations.
On the other extreme, a number of South Dakota counties were among those with the lowest rates of poverty for school-aged children at 2.9 to 11.6 percent. These counties are:
Nationally, according to U.S. Census Bureau estimates, the poverty rate for school-age children had no statistical change in 2,199 counties between 2007 and 2013 while 928 counties experienced an increase and 15 showed a decline.
The statistics are from the Small Area Income and Poverty Estimates program, which, according to the Census Bureau, provides the only up-to-date, single-year income and poverty statistics for all counties and school districts — roughly 3,140 counties and nearly 14,000 school districts nationally.
"County school-age child poverty rates are still above their prerecession levels in metropolitan areas of California, Nevada, Arizona, Florida, Georgia, the Carolinas, as well as the coastal areas of the Northeast and Great Lakes states," said Wesley Basel of the Census Bureau's Small Area Estimates Branch. "State and local programs use these statistics for distributing funds and managing school programs."
The Census Bureau says the findings show there were large concentrations in the South and West of the 972 counties with poverty rates statistically above the national average of 20.8 percent for school-age children
Conversely, 902 counties had poverty rates for school-age children that were statistically lower than the national rate. In five states, 80 percent of counties had rates lower than the national rate: Connecticut, New Hampshire, North Dakota, Rhode Island and Wyoming.
The official poverty statistics for the nation were released in the fall showing a decline in the poverty rate for children under age 18 from the previous year for the first time since 2000.
Residents of rural areas in the United States tend to enjoy better mental health than do their urban counterparts, reports the Daily Yonder.
Researchers who studied mental health data gathered by the County Health Rankings found that peak mental health is typically found in rural areas that are near an urban center, while the urban centers tended to have the poorest mental health.
At the same time, much of South Dakota and the Upper Great Plains reported some of the nation's best mental health. In South Dakota, only Lake County residents reported mental health in the poorest category. They reported 4.4 poor mental health days per month, on average per capita. That is just enough to push Lake County in the worst cateogry, which ranges from 4.4 to more than 10 poor mental health days per month.

Shannon County’s population shrunk by 666 according to the most recent statistics. With a total of 1,202 people exiting the county and an influx of only 388 people, the county experienced a net loss of population due to migration. The majority of outbound migrants remained in South Dakota, specifically in Pennington (353) and Bennett Counties (105). Many moving out of state headed for Alaska (192), with a significant percentage ending up in Anchorage.
Those who do chose to relocate to Shannon County are most likely to be from Pennington County (81). The next largest county contributor isn’t even located within South Dakota borders. Denver County, Colorado held the second spot, contributing 36 migrants to Shannon County.
Other interesting Shannon County estimations include:
The above migration statistics were taken from the Census Flows Mapper and its most current data from the American Community Survey (2008-2012).
South Dakota Adults Grow in Population, Youth Stagnates
According to the US Census Bureau, the overall South Dakota population continues to age, and the trend shows no sign of reversing in the near future. Since 1990 the adult population between the ages of 18 and 64 has increased from 56.8% of the overall population to 59.3% in 2016. Additionally, the fraction of adults aged 65 and older has grown from 14.7% of the state's population in 1990 to 16.0% in 2016.
At the same time, the US Census Bureau reports that the relative number of younger South Dakotans has declined. Children between the ages of 0 and 4 years old have gone from 7.8% of the population in 1990 to 7.1% in 2016. Similarly, the fraction of children between the ages of 5 and 17 years old has dropped from 20.7% in 1990 to 17.6% in 2016.
When looking at sheer numbers, the 18- to 64-year-olds trounce the other groups, increasing by 118,151 between 1990 and 2016, compared to increases of only 36,474 for those 65 and older, 6,865 for the 0- to 4-year-olds and 7,960 for the 5- to 17-year-olds.
The overall aging trend in the state is due to the aging of the “baby-boomer” generation, and nowhere is this more evident than in the growing number of senior citizens in the state. The oldest South Dakotans, those 85 and older, have been growing as a subset of the 65 and older cohort. The number of these most senior citizens increased from 19,226 in 2010 (2.4% of the statewide population) to 21,516 (or 2.5 percent) in 2016.
The statewide retirement-to-working-age ratio (the number of retirees divided by the number of working-age adults) indicates that retirees account for a growing percentage of the population. The statewide retirement-to-working-age ratio has risen from 23.6% in 2010 to 27.0% in 2016. This ratio is even more pronounced in the Black Hills region, where the ratio was 28.9% in 2016—a substantial increase over the 22.7% ratio in 2010.
While the state as a whole appears to be aging, Census data indicates that some counties are much greyer than others. With a median age of 54.2, Custer County had the Rushmore State’s oldest residents in 2016. In contrast, Todd County had the state’s youngest population with a median age of 24.4. The chart below shows the three oldest and youngest counties in the state.
