The West is home to fewer children than it was five years ago, according to new census data.
Why it matters: Portland's been grappling with this demographic shift for years — declining classroom enrollment, an aging population, slower population growth — and it could drastically reshape the local economy.
By the numbers: The West's under-18 population fell by more than 1 million, or 5.7%, between 2020 and 2025 — the largest decline of any U.S. region, according to new Census Bureau Vintage 2025 estimates reviewed by Axios.
- Nationally, the under-18 population fell 2.4% during the same period.
- The South was the only region to see growth in its child population, adding about 304,000 under-18 residents in that five-year period, fueled largely by migration from other parts of the country.
Zoom in: As Portland's child population continues to shrink, officials are adapting in order to serve fewer young families while preparing for an older population.
🏫 Schools: Enrollment in Portland Public Schools has dropped steadily since 2020, leading the district to confront severe budget shortfalls, school closures, classroom consolidation and cuts to special programs.
🍼 Child care: Changing demographics led Multnomah County to reduce its 2030 enrollment projections for its Preschool for All program by roughly 30% last year.
- Meanwhile, Oregon's child care system is already struggling under workforce shortages, high costs and a lack of day care facilities. Providers operate on thin margins and a smaller pool of children could make it harder for some centers to stay open.
💼 The economy: Fewer children today means fewer workers tomorrow. The Portland metro's natural population growth has nearly stalled — falling from 13,900 more births than deaths in 2001 to just 3,400 in 2024. That leaves the region increasingly dependent on migration to support its workforce and economy.
- Plus: As Portland's population ages and begins to retire, the imbalance between older and younger generations is likely to strain affordable housing, health care systems and family caregivers.
The bottom line: Whether Portland can attract and retain young families may become one of the region's defining economic challenges.
