South Dakota Population 2017


Situated in the northern midwest, the US state of South Dakota is the 17th largest in the Union but has a relatively sparse population by comparison. Like its near neighbor North Dakota, the state's geographical features do not lend themselves to mass urban settlements, and a lack of choice when it comes to employment has seen an exodus to other parts of the country. In 2016, the estimated population of South Dakota is 858,469.

The current population of South Dakota is estimated at 858,469, which shows an increase from the 2010 Census. The state currently enjoys a growth rate of 1.17%, which ranks 11th in the country.

The last national census in the United States took place in 2010, and it was confirmed at the time that the population of South Dakota was 814,180, which represented a rise of nearly 8% on the numbers declared in 2000. An estimate of the state's population from July 2015 places it at 858,469, which makes South Dakota the 46th most populous state in the US.

Not only is South Dakota the 46th largest state in the US in terms of numbers, it also shares that rank with regards to population density. The state is a vast area, covering 77,116 square miles, which makes it the 17th largest state in the country by area, but for each of those square miles, there is an average of just 10.7 people. It's the 46th most densely populated state in the US.

Like other Great Plains states, South Dakota has seen a dropping population in its rural areas for many decades in a phenomenon known as "rural flight." Between 1990 and 2000, 9 counties in the state saw a population drop greater than 10%, with one county losing 19% of its population in just a decade.

Despite this, many areas of South Dakota are seeing increases in population. The Sioux Falls area, large counties along Interstate 29, the Black Hills area and many Indian reservations have enjoyed growing populations. Lincoln County in particular is notable as the 9th fastest growing county (in terms of percentage) in the country.

South Dakota Population History

The first recorded population figures date from 1860 when it was reported that 4,837 South Dakotans were already living in the area. Ten years later those numbers had jumped to 11,776, but the biggest spike in South Dakota population history was to follow as a leap of over 700% took those numbers to 98,268.

By the beginning of the 20th century, the population of South Dakota had reached 401,570, and while the overall picture throughout the 1900s was one of growth, there have been censuses where numbers fell on a decade by decade basis.

The blame for this was put firmly on a phenomenon called rural flight which saw a ‘brain drain’ of sorts, particularly among University graduates who sought a future away from the unpredictable life of subsistence farming.

South Dakota Population Growth

South Dakota is enjoying steady growth that is expected to continue, and it is actually growing faster than the country for the first time in more than 50 years. It's believed this growth is due to more working-age adults, as well as the high birth rate that exceeds the national average, a low death rate and migration to the area as manufacturing jobs have increased 458% from 1970 to 2000, while retail grew 79% and finance jobs 137%.

In recent years, the population of South Dakota has returned to healthy growth, and from 1980 onwards, there has been an increase in numbers. Could the most recent increases be due to the growth of the internet, the rise in remote working and therefore a reduction in the need to leave the state to seek work elsewhere?

Whatever the reasons may be, with growth levels around 8% between Censuses at present, the population of South Dakota should be on its way to the next milestone in 2020.
