Indiana Population 2018

6,699,629

From the latest Census estimates and the current rate of change, we estimate Indiana's population in 2018 at 6.70 million.

Yearly estimates are given for states within the US, and the most recent suggests Indiana’s population had increased to 6,619,680 in 2015. The state has a population density of 181 people per square mile, which ranks it as the 16th most densely populated state in the country. Indiana has a 2016 growth rate of 0.33%, which ranks 29th.

Indiana was admitted as a state to the US in 1816, but population figures can be traced back to 1800. As for the present day, the last official census within the United States took place in 2010 and at the time, the population of Indiana was declared at 6,483,802, a rise of 6.6% on the numbers from 2000.

Indiana Population Density and Demographics

In terms of pure land mass, the state of Indiana covers an area of 36,418 square miles (94,321 square kilometers), and this makes it only the 38th largest state in the country by area. However, Indiana ranks much better in terms of numbers and population density.

Indiana Population History

Indiana was included in the Northwest Territory (1787) but became a separate territory in 1800. At that time, in addition to most of present-day Indiana, the Territory included all of Illinois and Wisconsin, the western half of Michigan, and northeastern Minnesota. In 1802 the boundary with Ohio was altered and eastern Michigan was added, but Michigan Territory was separated in 1805 and Illinois Territory in 1809, leaving Indiana Territory with the present State area except for a narrow band along the northern border; the territory also included a portion of the Michigan Upper Peninsula. On December 11, 1816 Indiana was admitted as a State with essentially its present boundaries.

In 1790 the Northwest Territory had no census coverage. The 1800 census of Indiana Territory enumerated scattered communities in southern Indiana, southwestern Illinois, northern Michigan, and Wisconsin; the populations reported from present-day Illinois and Michigan are shown under those States. In addition, Hamilton County, Ohio included some population in what is now Indiana. In 1810, census coverage of Indiana Territory was limited to southern Indiana, and coverage did not include the whole State until 1830.

Indiana Population History

Indiana is situated just inside the eastern half of the United States, and statistics show that the state was a little slow to embrace the huge waves of early settlers that arrived to the country in the 18th century.

From the figures declared in 1800, the population of Indiana was shown to be 2,632 but just ten years later, it had increased by phenomenal proportions and a rise of over 800% took the total to 24,520.

By the time of the nationwide census of 1830, Indiana had been admitted to the United States, and a further substantial growth of over 500% in ten years took the total number of residents to 147,178. Those were by far the biggest population spikes, but further large increases had taken Indiana’s population to over 2.5 million by the beginning of the 20th century.

From this point, growth slowed down to a great extent, but it remained healthy and constant to the stage where 6.6 million people make up the population of Indiana in 2016.

Indiana Population Projections

In many ways, Indiana is a fairly unremarkable state in terms of its population statistics, but it is experiencing healthy growth nevertheless. By increasing at the same rate, it is estimated to reach 6.85 million people by 2020. By 2030, Indiana is expected to break 7 million people.

For the past two decades, population growth in Indiana has been concentrated in counties surrounding the capital city of Indianapolis. Four of the five fastest-growing counties are in that area: Hamilton, Hancock, Johnson and Hendricks. The 5th county, Dearborn County, is located near Cincinnati, Ohio. Hamilton County remains the fastest growing county in Indiana, as well as the fastest growning in the bordering states of Ohio, Kentucky, Michigan and Illinois. It's the 20th fastest growing county in the United States, and this trend is expected to continue as the Indianapolis metropolitan area continues to expand beyond 2016.
