Matching like to like–cohort addition

Framing up the data around issues can highlight one view while smothering another. All the numbers are correct, it is the sorting and comparing which is all a kilter. Take for instance the topic of home ownership. Here are the rates by state provided by FRED. Minnesota looks great!

Now let’s look at how homeownership rates broken down by county. You will notice that the highest homeownership rates are in out-state Minnesota and the lowest rates in the counties which make up the Twin Cities metropolitan area–outlined in purple.

Since the rural communities tend to be older, it will be no surprise that homeownership is also highest amongst the middle to late middle age population. The Millennials, until just recently, have taken lack of interest in homeownership. Whereas 77-80% of the Boomers or Silent generation live in their own home, only 43% of those under 35 years of age have chosen buy a home. Younger folks are more likely to be attracted to the metro area.

To review, the data shows that as a state we have a high homeownership rate. Overall Minnesotans are confident in their ability and desire to own real estate and pay relatively high (ranked 19th) property taxes. Homeowners trust the cities, counties, school districts and, (for a smaller portion) the state in the use of the funds to provide services. The youngest group of adults, however, are running well below this rate, but in line with the national average.

No tricks or mirrors so far.

But what about these headlines? Are they accurate? Racial inequality in Minneapolis is among the worst in the nation – The Washington Post, Homeownership gap plays a huge part in race inequities – StarTribune.com, Why Black Homeownership Lags Badly in Minneapolis – WSJ

Each article frames the data in the same way. Minnesota is a horrible place to live for African Americans as exemplified in the homeownership gap of 51%, which is the worst in the nation.

In the Minneapolis metro area, 77% of white residents own homes, compared with 25% of Black residents—a 52-percentage-point difference, larger than in any other major U.S. city, according to an analysis of census and survey data by the Minnesota State Demographic Center, a state agency.

What’s interesting is the black population in Minnesota has increases by more than 36% in the past ten years.

Between 2010 and 2018, the fastest growing racial group in Minnesota was the Black or African American population, which grew by 36%, adding more than 96,500 people. Second fastest was the Asian population, which grew by 32%, adding 69,800 people, followed by the Hispanic or Latin(x) population, which grew by 24%, adding 59,000 people. (Black or African American and Asian race groups are that race “alone” and not Hispanic or Latin(x)).

So if things are so bad, why all the in-migration? Maybe there is a need to look at the numbers a little more closely. Consider the breakdown of Minnesotans by age. You will note that people of color skew strongly to Millennials or younger.

So wouldn’t the proper framing be to compare Minnesota’s homeownership rates by age cohort? I don’t have access to the numbers by generation, nor the time a journalist could devote to such calculations, but it seems erroneous to ignore variance between the groups. It seems flat out wrong to calculate rates of ownerships for African Americans who simply don’t live in our state. It’s true, that even with such an adjustment, there is still a gap. The spread is in the 18% (43%-25%=18%) range instead of the noteworthy gap of 51%.

Perhaps it is useful to use the inflated figure in order to get people’s attention. I believe ownership is the answer to extending trust between citizens and all the public endeavors in a neighborhood. I’ve also devoted many hours of unpaid labor with that mission in mind. But there are negative outcomes from fooling with the numbers too.

They discredit the built up capital that hundreds of people have devoted to the cause in good faith.
