Day 2 · Indicator framework

Prosperity is not mobility.

If a metric does not follow the same people over time and does not reference their starting position, it is a prosperity indicator, not a mobility indicator. Both belong on the table — but only one tells you whether a person born at the bottom is actually moving up.

You can post record job numbers while mobility is flat. A cross-sectional snapshot hides who is churning and who is stuck. The anchors below are organized so the room can tell the difference — and pull the levers that matter.

Filter by track:

Do kids out-earn their parents? Do they change their rank?

Absolute upward mobility · Birmingham vs U.S.

Children raised by Birmingham's lowest-quintile families out-earn their parents in real terms by 9.7%. The same national cohort earns 6.2% less than theirs. This is Chetty's absolute-mobility measure — the same families tracked from childhood into adulthood.

Relative mobility (IGE)

How tightly a child's income rank tracks their parents'. Lower = more mobility. The U.S. sits near 0.34 (high stickiness); Denmark ~0.15. The rank-rank slope is the standard research measure of how much your starting position determines where you end up.

Earnings progression
True mobilityDesign metric — pull quarterly
Same-person wage trajectory (not placement counts)

Placement tells you someone got a job. Progression tells you whether they are still there in 18 months and earning more. The right question for workforce programs is 'what were they earning at intake, and what are they earning 24 months later?' — same individual, real dollars.

Not 'did they get placed' but 'are they still there, above the self-sufficiency wage, 18 months later.' Jefferson County's self-sufficiency wage for one adult + one child is roughly $27/hr (MIT Living Wage 2024). Placement without retention is churn.

Income parity without wealth parity is not mobility.

Asset & wealth

Homeownership gap

Black vs white homeownership · Jefferson County

Homeownership is the primary vehicle of wealth accumulation in America. Nationally the Black–white ownership gap is ~28 points (44% vs 72%). Jefferson County's gap tracks close to national. Income parity without ownership parity leaves the wealth gap intact.

White families hold roughly six times the wealth of Black families at the median (~$285K vs ~$45K, SCF 2022). Income parity can coexist with enormous wealth disparity — which is why any mobility conversation that stops at income is incomplete.

Economic Connectedness (EC) · Chetty 2022

The share of a lower-income person's friends who are higher-income. Chetty's 2022 Nature papers found EC out-predicts school quality and family structure for upward mobility. It is the single most actionable mobility variable — a city can deliberately engineer where people work, learn, and gather.
