OECD 2025 Survey
Housing & Fertility Lab
From academic curiosity to boardroom concern

When homes become assets, families wait.

OECD’s 2025 Economic Survey of Sweden links rising housing prices to falling fertility. It’s not just cost—it’s the commodification of housing. Young adults choose between mortgage payments and family planning, creating a self-reinforcing economic loop.

Sweden: Hesitation to start family due to housing

+350%

Proportion of young adults reporting housing shortage as reason to delay childbearing. Source: OECD 2025 Survey of Sweden.

The commodification shift

Housing is treated primarily as a financial asset rather than a social good. That structural shift changes life decisions.

Cost Burden

Renters in Sweden’s lowest income quintile spent 41.5% of income on housing in 2019—well above OECD average of 32.5%.

Price vs Fertility

House price-to-income ratios rose sharply since 2015 while total fertility rates declined across OECD.

Cross-country evidence

Higher housing cost burden correlates with lower fertility. Sweden is an outlier on burden, not on direction.

The self-reinforcing loop

Unaffordability → delayed fertility → smaller future workforce → pressure on public finances & growth → further affordability stress for young cohorts.

1

Housing costs consume disposable income, raising entry barriers to family formation.

2

Fertility delay reduces long-run labor supply and dependency ratios worsen.

3

Fiscal strain limits housing investment, perpetuating scarcity.

Housing Unaffordability Cost burden ↑, access ↓ Delayed Fertility Family formation postponed Fiscal & Growth Pressure Smaller workforce, aging
