Maryland Population 2018


Situated on the eastern tip of the USA, Maryland is one of the smallest states in the country. However, what it lacks in size it more than makes up for in population numbers and density. Overall, this is one of the busiest and most bustling areas in the union. As of 2018, Maryland has an estimated population of 6.08 million.

The last set of confirmed population figures occurred during the 2010 Census, showing there were 5,773,552 people living in Maryland -- a rise of 9% from the figures declared in 2000. Further estimates continue to suggest that the population of Maryland in 2016 is 6,006,401. Maryland also has a healthy population growth rate of 0.96%, which ranks 20th in the country.

With a surface area of just 12,407 square miles, (32,133 square kilometers), Maryland is only the 42nd largest state in the USA in terms of land mass. It is, however, one of the most populous and most densely populated states in the whole country. A 2016 estimate of the population places just over 6 million people in the state, which makes it the 19th most populous state in the country.

Looking at those numbers, it isn’t hard to establish that this must be a very densely populated area indeed. In fact, there are about 594 people per square mile in Maryland. This population density makes Maryland the 5th most densely populated state in the USA.

Montgomery County is the most populated county in the state with 1.04 million residents, while Kent County was the least populated with just 19,787 residents, according to the 2015 Census estimates. Southern Maryland has grown faster than the rest of the region with a 21% increase between 2000 and 2010, compared to just 9% for the state as a whole. Most of the state's population lives in the central area of the state in the Washington and Baltimore metropolitan areas, while the Eastern Shore remains rural.

Maryland Population History

Maryland was one of the 13 original States. It helped form the District of Columbia in 1791; its boundaries have been substantially unchanged since then, although the Maryland-West Virginia boundary was in dispute as late as 1910.

Census coverage has included the entire State from 1790 on. The 1790 population includes the present area of the District of Columbia, separated from Maryland in 1791. The 1840 results for Montgomery County are from a re-enumeration of the population as of 1840, conducted in 1841.

The Growth of Population in Maryland

As early settlers began to arrive in the New World, the eastern states began to be colonized first, and Maryland was no exception. In the first set of recorded figures available, it was shown that in 1790, 319,728 people were already living in the state. By comparison, many states on the western edge of the US recorded population numbers that barley breached four figures.

From this point, the population of Maryland grew by healthy and steady percentages on a census by census basis. By the time that the 1800s faded away, the 1900 census recorded that the population had comfortably exceeded 1 million, with a final, confirmed figure of 1,188,044.

Unlike other states, however, that growth failed to ever settle down and continued to show significant rises, taking us to the present day where in 2016, Maryland's population has surpassed 6 million.

Natural Growth

Figures relating to natural growth tell the story of Maryland’s ever-expanding population, and in 2006, statistics were released that showed a net gain of 319,221 people since the Census of 2000. This included 464,251 births in the six year period, 275,093 deaths and a net migration of 116,713.

Based on these growth levels, the state predicts its population will reach 6.3 million by 2020.
