Michigan Population 2018
As of 2018, the state of Michigan has an estimated population of 9.99 million.
The last confirmed set of population figures date from the countrywide census of 2010 when it was declared that there were 9,883,640 people living in Michigan. Those figures from 2010 represented a small loss of less than 1% compared to the numbers declared at the 2000 census.
In 2015, it was estimated by the US Census Bureau that the population had risen to 9,922,576. This reflects a less than 1% increase in population since the 2010 Census, which puts Michigan in 45th place in terms of population growth.
Michigan Area and Population Density
With a total land mass of 96,716 square miles, (250,493 square kilometers), Michigan is the eleventh biggest state in the USA by area. The land is fairly densely packed, although not exceptionally so -- for every square mile of Michigan territory, there is an average of 174 people (67.1 per square kilometer). Those figures leave Michigan ranking 18th in terms of population density.
Largest Cities and Counties in Michigan
The largest city in Michigan is the Motor City, Detroit. The 2010 census confirmed that it was home to 713,862 people. This number has decreased to just over 677,000 according to 2015 estimates. If you take a look at the population of Detroit, it’s clear that this is where much of the state’s demographic problems lie. At its peak in 1950, there were 1.85 million people living in the city. In 2016, that number has declined by over one million people. Many of those leaving the city are actually not moving far -- they move out toward the suburbs. But following the city's bankruptcy filing and urban decay, it’s likely that some are packing up completely and moving out of state, which doesn’t help the state’s overall population figures.
Age/Sex, Race, Religion
The median age of the population in Michigan is 39.5 years of age. The gender ratio is approximately 50.8% female and 49.2% male.
In term of religious preference across the state, Michigan comes in with 70% preference to Christian based faiths, 5% are affiliated in non-Christian based faiths, and 24% are unaffiliated with any religion.
Michigan Boundary, Census and Statehood History
Michigan was part of the Northwest Territory established in 1787. When Indiana Territory was created in 1800 it included the west half of lower Michigan and nearly all of the Upper Peninsula, leaving the remainder of the present State in the Northwest Territory until 1802, when the eastern portion also became part of Indiana Territory. Michigan Territory was established in 1805, but nearly all the Upper Peninsula remained in Indiana or Illinois Territories. In 1818 Michigan Territory's boundaries were extended to include the rest of the Upper Peninsula and all of present-day Wisconsin and northeastern Minnesota. In 1834 the Territory was expanded still further to stretch to the Missouri River, including the rest of Minnesota, Iowa, and the eastern Dakotas. Michigan Territory included a northern strip of Indiana until 1816, and it also governed a narrow strip of what is now northwestern Ohio which was claimed by that State. This was ceded to Ohio in 1836, and Michigan was admitted as a State on January 26, 1837 with essentially its present boundaries.
In 1790 the Northwest Territory had no census coverage. In 1800 coverage of the present State included only the Detroit area (Wayne County, Northwest Territory) and some persons at "Machilamackanack," Indiana Territory. Coverage in 1810, 1820, and 1830 expanded in the Lower Peninsula and included population in the strip that was ceded to Ohio in 1836. The 1820 and 1830 censuses also included some settlements in present-day Wisconsin, shown under that State. The 1840 census covered all parts of the State.
