Using Census data, this post examines the visual correspondence between income and educational attainment across the region. It clearly portrays the continuing association between these two critical variables with one region of high income and high educational achievement arching across the region from Washtenaw County, through Western Wayne County and up through Oakland County and western Macomb County. South of this is a region of lower income and educational attainment with a few islands of higher income and achievement. In all, this represents a strong and largely consolidated portrait of segregated classes in this region.
In Southeastern Michigan the City of Highland Park had the lowest median income at $17,250, with 33 percent of the adult population only having a high school diploma. In terms of educational attainment in Highland Park, those who had some college education or an associate’s degree represented the highest percentage of residents, as opposed to the other categories (less than high school, high school education, bachelor’s degree, graduate or professional degree). On the opposite end of the spectrum, the City of Bloomfield Hills had the highest median income at about $173,000, with the largest percent of its adult population having a graduate or professional degree (38%). Such trends are not unique to Highland Park or Bloomfield Hills.
Above the maps show what the median income of each community is with an overlay that shows what the percentage of educational attainment is at five different levels. These levels are: graduate degree, bachelor’s degree, associate’s degree or some college, high school diploma or an equivalency and less than a high school diploma. The overall purpose of each map is to present an image on how educational attainment and at each level may, or may not, relate to the median income.
When looking at the maps above we see that the communities that have more than 18 percent of its adult population with graduate or professional degrees tend have median incomes above $77,000. In total, there were only 10 communities, out of 46, where more than 18 percent of its adult population had graduate or professional degrees but the median income was below $77,000. Of those 10 communities, the City of Ypsilanti had the lowest median income at about $31,000 and 18 percent of its adult population had a graduate or professional degree. The community with the highest percentage of adult residents with a graduate or professional degree is Ann Arbor, where both the University of Michigan and the University of Michigan Hospital are located. The median income for Ann Arbor in 2015 was $103,000. There was no community in Southeastern Michigan where more than 30 percent of the adults had a graduate or professional degree and had a median income below $95,000.
On the opposite side of the spectrum, there are 154 communities in Southeastern Michigan where 10 percent or more of the adult population had less than a high school education in 2015. The City of Hamtramck had the highest percentage of adults without a high school education at about 31 percent; the City’s median income was about $23,000. There are nine communities in the region where 20 percent or more of the population had less than a high school education. Of those nine communities, with the exception of Lincoln Park, none had a median income above $33,000. The median income in Lincoln Park was $41,000 in 2015. The City of Detroit is included in that list of nine communities, with a median income of about $26,000 and about 22 percent of its adult population having less than a high school education. Additionally, in Detroit, about 32 percent of the adult population had a high school education, and about 32 percent had some college education or an associate’s degree.
The percentage of Detroit residents with a bachelor’s degree was far lower than any of the statistics mentioned above. In Detroit, about 8 percent of residents had a bachelor’s degree in 2015. In terms of the percentage of residents throughout Southeastern Michigan with a bachelor’s degree, the average percentage was 18 percent and the median income was about $66,000.
Regionally, the community with the highest percentage of residents with a bachelor’s degree was the Village of Grosse Point at about 62 percent; the city had a median income of about $139,000. The City of River Rouge had the lowest percentage of adults with a bachelor’s degree at about 4 percent; it had a median income of approximately $26,000. In total, there were 46 communities in Southeastern Michigan where less than 10 percent of the population had a bachelor’s degree. Exeter Township, located in Livingston County, had the highest median income of the 46 communities that had less than 10 percent of its adult residents with a bachelor’s degree. The median income in Exeter Township was about $68,000.
Overall, this post shows that there is a correlation between median incomes and educational attainment, a deeper conversation that we will dive into next week. The maps and the data show that it is the communities with the higher percentage of residents with a bachelor’s degree and/or a graduate degree that have amongst the highest median incomes.
