Sources & methodology

Every number on this site, traced back to its dataset.

We make hard claims about how long Detroiters live. Hard claims require receipts. Below is the dataset, geography, and year behind each figure, with a link to the public source so you can run the query yourself.

How we calculate
  • All life expectancy and mortality figures are age-adjusted to the 2000 U.S. standard population so that places with different age profiles can be compared fairly.
  • Detroit figures are for the city proper, never the metro area. Metro-level numbers blend Detroit with wealthier suburbs and erase the gap.
  • Cause-specific rates are pooled across 2019–2023 to stabilize small annual counts, per CDC guidance on suppressed and unreliable rates.
  • The "three miles apart" distance is the straight-line distance from Detroit's northeast city limit to the nearest Macomb County residential area.
  • Where a figure is a D-Unit compilation rather than a single published statistic, we label it as such below.

Network relationships and corrections

The Network index states who owns, develops, funds, or trains for each institution. Below is the source behind each of those connections and why the relationship matters to a Detroit resident, business owner, or founder.

BAMF Health is a Grand Rapids company opening a second site in Detroit

Grand Rapids HQ · Detroit site at the Gratiot Life Sciences Building

Earlier copy on this site called BAMF a Detroit-based company. BAMF was founded in Grand Rapids at the Doug Meijer Medical Innovation Building; the Detroit facility is its second location, built with Henry Ford Health. The distinction matters for residents: hiring, training, and radiopharmacy operations are run from an existing Grand Rapids operation, not started from zero in Detroit.

MSU Research Center is the Henry Ford Health + MSU Health Sciences Research Center

$335M · 30-year Henry Ford Health partnership · opens 2027

The facility is not a standalone MSU building. It is a joint venture governed by a 30-year partnership between Michigan State University and Henry Ford Health on Third Avenue in New Center, which is why job postings and research roles appear under both names.

Michigan State University holds a majority ownership stake in the Fisher Building

Majority stake · MSU Detroit incubator space inside

Previously described only as a building that houses MSU space. MSU is an owner, not a tenant, which is why incubator terms and access for Detroit founders are set by the university rather than a private landlord.

TechTown Detroit is Wayne State University's incubator

Wayne State affiliate · MedHealth initiative

TechTown was founded by and remains affiliated with Wayne State University. Its MedHealth initiative is the specific program that connects founders and suppliers to health-system buyers, which is the relevant door for D-CONNECT and D-VENTURE referrals.

Bedrock is the developer of the Gratiot Life Sciences Building

Gratiot district master developer · UMCI co-developer with Related Companies

The building was listed without naming who controls it. Bedrock develops the Gratiot site and co-develops the University of Michigan Center for Innovation with Related Companies, which means Bedrock — not the health systems — holds the construction, trades, and facilities contracts Detroit firms can bid on now.

Ferris State University runs the academic pipeline into BAMF Health

Nuclear medicine and radiopharmacy training partnership

Added to the index because it is the named training route into the highest-paid roles at the Gratiot theranostics center. Without it, the career pages point to jobs with no visible credential path.
