South Carolina Population 2018

5,088,916

Situated on the southeastern tip of the United States, South Carolina is one of the smallest states in the country but has a high population density by comparison. It's estimated that South Carolina's population reached 5.09 million in 2018, up from 4.62 million at the 2010 Census. South Carolina currently enjoys a growth rate of 1.06%, which ranks 18th in the country.

The last set of confirmed population figures in the United States came with the nationwide Census carried out in 2010. At the time, it was confirmed that there were 4,625,364 people living in the state -- a rise of just over 15% on the figures declared in 2000. The Census Bureau estimates there are 5.09 million residents of South Carolina in 2018, making it the 24th most populous state in the entire country.

Like many states on the eastern edge of the country, South Carolina is densely populated in comparison to its relatively small size. The state has an overall surface area of 32,020 square miles (82,931 square kilometers) which makes it just the 40th largest in the US.

For every square mile of South Carolina territory, however, there is an average of 153.9 people. That figure makes the state the 19th most densely populated in the country.

The two largest cities in South Carolina are Columbia (pop 133,803) and Charleston (pop 132,609), followed by North Charleston (pop 108,304). These are the only cities in the state with a population over 100,000.

Interestingly, South Carolina's metropolitan statistical areas are much larger than they appear based on the central city populations. Because of South Carolina law regarding unincorporated areas around city limits, most city proper populations seem smaller than the actual size of the area.

For example, Columbia, Greenville and Charleston each have urbanized area populations between 400,000 and 550,000, with the metropolitan statistical area (MSA) populations exceeding 60,000. The Greenville-Spartanburg-Anderson area is by far the largest, accounting for 1.4 million of South Carolina's population.

South Carolina Population History

South Carolina was one of the 13 original States. By the time of the 1790 census it had essentially its current boundaries, with some later adjustments following improved surveys. The census has covered all of the State ever since 1790, except for a narrow strip of Indian lands on the northwestern border, first enumerated in 1820. The 1790 census was not completed in South Carolina until early 1792.

South Carolina Population History

In 1790, the population of South Carolina stood at an already healthy level of 249,073 and ten years later, at the start of the 19th century, those numbers had risen by just under 40% to 345,591. That was a significant rise, although it may not have been quite as substantial as other parts of the country were recording at the time.

The pattern of increases in the population of South Carolina continued to display healthy, if unspectacular, percentage growth and the numbers went beyond the one million mark for the first time in 1890.

In the 1900s, percentage growth slowed down to an extent but the overall picture was one of sustained increases through the end of the century. That has also continued to the present day where the South Carolina population is edging closer to the 5 million landmark in 2016.

South Carolina Population Projections

Natural growth and net migration in South Carolina is extremely healthy and there is nothing to suggest that this pattern will change in the years leading up to the next census.

Projections currently estimate South Carolina's population will just barely exceed 5 million by the 2020 Census, with a population over 65 that exceeds the national average.

South Carolina has the 5th highest percentage of Black or African American residents in relation to its total population, with the majority taking up residence in the Midlands and Low Country regions.
