| The City has experienced steady increases in population since 1825, when the original settlement of what would become Ann Arbor occurred. At that time the population of Ann Arbor was 25. By 1830, the population had increased to 300. By 1840, three years after Ann Arbor was approved as site the site of the University of Michigan, the population had swelled to 3,507. Both the City population and University enrollment continued to increase over the next several decades
The population of Ann Arbor doubled between 1950 and 1970. (Some of this population was gained through annexation of township land that increased the size of the City.) By 1980, the City contained 107,966 persons, an increase from 1970 of 8 percent. In the 70s and 80s, established boundary agreements limited the growth of the City land area. By 1990, the City population had increased by less than 2 percent from 1980, and between 1990 and 2000 there was a 4 percent increase in population.
Between the 1990 and 2000 censuses, Ann Arbor and Grand Rapids were the only two Michigan cities that did not experience depopulation in the urban core. To maintain the City infrastructure over time, to sustain essential services and environmental initiatives, a stable population must be maintained. |

*Prior to 1950, the Census Bureau considered college students to be residents in their parents’ homes. Since 1950, the Census has included students as residents of the communities in which they lived for most of the year. The Ann Arbor Planning Department has estimated the number of students not counted by the Census for each Census year from 1900 through 1940. These estimates were made from data supplied by The University of Michigan and the Ann Arbor Public Schools. For details, see Economic Base Report, Ann Arbor Planning Department, 1965, p. 73. The “total population” figure counts students as well as the more permanent population.

What is population?
Total population includes all individuals who live in the City of Ann Arbor jurisdiction.
Prior to 1950, the Census Bureau considered college students to be residents in their parents’ homes. Since 1950, the Census has included students as residents of the communities in which they lived for most of the year. In the above table, the Ann Arbor Planning Department estimated the number of students not counted by the Census for each Census year from 1900 through 1940.

What is Ann Arbor's population forecast?
A population forecast is the predicted population for Ann Arbor at a future date -- in this case, 2030.
The Southeast Michigan Council of Governments (SEMCOG) estimates that the 2007 population in Ann Arbor is just about the same as 2000 at 114,062, and forecasts that there will be 116,270 residents in 2030. While there is little predicted population growth, overall households in Ann Arbor are expected to increase as the average household size decreases.

How does population affect our environment?
The more people that live in the City, the more resources are needed to support their presence. However, total population and population growth do not offer an exclusive view of human demographic impact. Population density and distribution are also important. If growth occurs in areas that already contain support infrastructure-- for example in the downtown district of Ann Arbor -- this growth is not likely to cause as much environmental impact as growth that occurs along undeveloped stream corridors in less dense areas of town.
