1990-2017 Population Estimates
2000-2017 Population Estimates: The 2017 population estimates on this site orignate from the 2010 US Census population for Michigan. The 2010 population was bridged at the census block-level based on the National Center for Health Statistics bridged race methodlogy. The 2000-2017 population estimates by age, sex and bridged race were taken from the bridged, single-race estimates released by the National Center for Health Statistics (NCHS) in September 2017. The NCHS population was subsesquently adjusted for error of closure to the 2010 population.
The 2000-2017 Minor Civil Division (MCD) data were originally estimated in 2017 using US 2000 Census population estimates; Michigan birth and death certificate counts; and PopStats block-level migration estimates and population distributions of race. The 2000-2017 was adjusted for error of closure using the 2010 census.
About single-race estimates: Race information provided in the U.S. Census Bureau Summary File 1: 2000 Census of Population and Housing was collected differently than for the 1990 Census. That is, in the 2000 Census respondents could classify themselves as being of more than one race. As a result, race counts by the Census Bureau are not mutually exclusive. The National Center for Health Statistics and many other federal and non-federal organizations throughout the country still use forms that capture racial information in single, mutually exclusive categories. NCHS entered into an agreement with the Census Bureau to convert the Census Bureau's multiple-race resident population counts to single-race estimates. For more information on the methodologies used to develop these estimates visit: the National Vital Statistics System, U.S. Census Populations With Bridged Race Categories.
1990-1999 population estimates: The 1990-1999 population estimates by age, sex and race provided on this site are taken from the bridged, single-race estimates released by the National Center for Health Statistics (NCHS) in July, 2010. The U.S. Census Bureau produced these revised intercensal estimates for NCHS by using the bridged single-race methodology described above.
The 1990-1999 estimates produced for NCHS did not break the 15-19 age group into two commonly used age groups: 15-17 and 18-19. Until this division becomes available from a demographic source, the Division for Vital Records and Health Statistics of the Michigan Department of Community Health have made interim estimates for these two age groups. Using estimates of the populations released by NCHS for the years 2000 through 2017, average proportions of 15 through 17 year olds and 18 through 19 year olds within each geographic area were calculated by race, sex and age group. These average proportions were applied to the 15 through 19 year old populations provided for the earlier years to obtain the estimated 15 through 17 year old and 18 through 19 year old populations for those years.
Data Source: The Michigan Department of Community Health, Division for Vital Records and Health Statistics prepared the tables available on this site by using population estimates developed as stated above. Population estimates are subject to error due to the limitations of available data and demographic methodologies. The average level of error increases in estimates for geographic entities with smaller populations and especially for population subgroups within those geographic entities.
Geographic Area Reporting: This site provides population estimates for the State of Michigan, all Michigan counties,Michigan local health departments and the larger MCDs in Michigan. Estimates for the population served by Detroit City Health Department and Wayne County Health Department was estimated by Michigan Department of Community Health, Vital Records and Health Statistics. The population estimates developed for NCHS did not delineate estimates below the county level.
Updating: Population estimates for this Web site will be updated when additional bridged population estimates become available. Additions anticipated include more detailed breakouts for certain age groups and estimates for cities and townships with at least 10,000 population.
