Data
A desk for sourced statistics, charts, comparisons, and the methods behind them.
Every figure should carry a source, geography, period, and retrieval date. If it cannot, it does not belong on the homepage.
The first published chart is an OECD price-to-income index comparison. Adequacy numbers come from UN-Habitat. National construction and price series come from the named agency, not from a blended world dashboard.
Each figure carries a geography, period, and named source. None of these is a global median home price.
People lacking adequate housing
2.8 billion
people
UN-Habitat 2024 Annual Report. 'Adequate housing' is a rights-based concept, not a single dwelling-unit count. Earlier UN-Habitat papers have used a range of 1.6–3 billion.
OECD average price-to-income index
114.8
index, 2015 = 100

OECD real house prices vs. a decade earlier
+40%
real price change, OECD average
OECD states that real house prices increased by over 40% over the past decade on average across the OECD. This is an average of member countries, not a global median price.
Low-income OECD tenants overburdened
1 in 3
share of low-income tenant households
OECD: on average, one in three low-income tenant households spend over 40% of disposable income on rent. Overburden is higher than half in some countries, including the United States.
