What Happened?

Federal money for building new train and bus lines could shift toward communities with higher marriage and birth rates under a proposal that has not yet become final. The Congressional Research Service (CRS) published a report examining the Federal Transit Administration (FTA) proposal to add birth and marriage rate bonuses to transit funding. ​

The FTA funds transit construction through a program called Capital Investment Grants (CIG), which pays a share of the cost of building new light rail lines and other fixed rail projects. Projects rated medium or higher would start at a 40 percent federal share, adjusted up or down by ratings on six criteria including cost effectiveness and congestion relief; federal law caps the share at 60 percent for New Starts projects and 80 percent for Small Starts and Core Capacity projects.

The FTA published the proposed changes on Oct. 1 in the Federal Register. Under the proposal, a project corridor would earn five extra percentage points for birth rates more than one percentage point above the national average, and another five points for marriage rates clearing the same threshold, each measured using Census Bureau tract data within a one-mile buffer around the corridor.

Why Does it Matter to Me?

Those two bonuses together add up to 10 percentage points, equal to the full penalty a project receives for a medium-low cost-effectiveness rating under the proposed scoring table. That means a project in a high-marriage, high-birth-rate area could have its weaker cost score offset by demographic bonuses.

The CRS report notes that critics point to research indicating that places with relatively high birth and marriage rates tend to be farther from urban centers, have higher car ownership, and lower transit use. Residents of such places are also more likely to be White and less likely to be Black or Hispanic, the report notes.

Both Sides, Now

The FTA says the proposed revisions are meant to streamline the CIG process and improve accountability. The proposal traces to DOT Order 2100.7, issued by the Department of Transportation on March 10, 2025, which directs the agency to give preference, where practicable and consistent with law, to communities with above-average marriage and birth rates.

Critics raise concerns about what the FTA's proposed transit funding formula would do in practice. A study published in *Findings* on Dec. 19, 2025, found that using marriage and birth rates to distribute transportation funding would shift money away from lower-resourced, racially diverse populations and toward predominantly White areas.

A new Congressional Research Service report raises questions about whether demographic bonuses could offset weaker project performance scores.

What Happens Next?

The public comment period runs until Nov. 16, giving the public 46 days from the Oct. 1 Federal Register publication to weigh in. The public comment period runs until Nov. 16, and the policy has not been finalized. Congress can also act through legislation or oversight to advance or block the changes, according to the CRS report.

Will the FTA finalize a formula that lets demographic factors outweigh a project's transit performance, or will Congress or public comment push the agency to revise it?
