SPM child poverty rate, 2027

The SPM child poverty rate for 2027 is dominated by the configuration of refundable credits under whatever tax regime is in force, plus the labor market. The CTC is the single largest policy lever — it directly raised the CTC sensitivity of SPM child poverty by roughly 4 percentage points during the 2021 expansion. The 2027 reading depends critically on how TCJA-extension legislation resolves.

Labor-market path is close to neutral for child poverty at this baseline — the 4.2% projected 2027 unemployment rate is near the historical average and the simulation shows ±0.3pp on child poverty over the [3.8%, 4.7%] band.

House passed a TCJA extension package in March. Senate markup is expected Q3. Conditional on the Senate moving a vehicle, full extension is the modal outcome but partial scaling (especially on CTC refundability) is a live possibility. Weighting:

P(full TCJA extension) = 0.65 · P(partial extension) = 0.20 · P(expiration) = 0.15

E[SPM child poverty 2027] = 0.65·11.4 + 0.20·12.2 + 0.15·13.1 = 11.83

The resolver is the Census Bureau's first published SPM poverty rate for people under age 18 for calendar year 2027. This is not the official poverty measure: SPM resources add taxes, refundable credits, and noncash transfers, and subtract necessary expenses including medical and work expenses, with thresholds adjusted for housing tenure and geography.

Base-rate/reference-class anchor: absent a new 2021-scale refundable-credit expansion, the most relevant outside-view level is the post-expiration 2022-2024 range of 12.4 to 13.8 percent, with more weight on 2023-2024 because SPM thresholds, rent, medical expenses, and benefit take-up had mostly normalized after the pandemic emergency period.

Level and momentum: the recent level is already slightly above the 2019 pre-pandemic rate of 12.6 percent, and the 2023 to 2024 movement was essentially flat at +0.1 percentage point. That argues against extrapolating a large trend increase from the 2021-to-2022 jump, because that jump mostly reflected policy expiration rather than ordinary poverty momentum.

Policy mechanism: the child SPM rate is unusually exposed to refundable tax credits, SNAP, school meals, housing subsidies, medical expenses, and child-care/work-expense deductions. For 2027, my central case assumes no broad permanent 2021-style child allowance is in force for the full year, so taxes and transfers keep the rate near the post-pandemic plateau rather than returning to 2021's 5.2 percent.

Counter-consideration: a material labor-market weakening by 2027 or benefit cuts could push the rate above 17 percent, while a large refundable child-credit expansion, unusually strong real wage growth for low-income families, or lower out-of-pocket medical and child-care costs could move it below 12 percent.

Point calculation: start from a weighted recent baseline of 13.7 percent using 2022-2024 values, add +0.3 for loss of residual pandemic-era supports and higher SPM expense pressure by 2027, add +0.2 for recession/policy asymmetry because downside poverty risks are larger than upside income surprises, giving 14.2 percent. Interval: using the non-2021-reversal post-expiration evidence, 2022 to 2023 was +1.3 pp and 2023 to 2024 was +0.1 pp, while 2019 to 2024 was +1.2 pp; I treat roughly +/-2.5 pp as normal 80 percent uncertainty around 14.2, then widen and right-skew judgmentally for tax-credit, benefit, and labor-market tail risk to 11.5 to 17.4.

Review disposition: accepted the resolution-date critique by no longer presenting 2028-09-12 as verified and by making the rule bind to the actual first Census print, with 2028-09-30 used only as an operational resolution deadline because the official 2028 calendar entry was not available. Accepted the interval critique by making the volatility basis and judgmental widening explicit; accepted the table-numbering and numeric-tail clarifications.
