Do Unemployment and Women's age at first marriage go together across countries?

Across 40 countries the link before adjusting for anything is r = +0.33, on a scale from -1 (opposite) to +1 (in step). A version that uses only each country's rank gives +0.35.

Does the link hold within countries over time, not just across countries?

Comparing each country only with itself across 2001-2021, and setting aside what happened worldwide in each year, the link is +0.113 (41 countries, 693 country-years). Using year-to-year changes, it is +0.046.

Does Unemployment cause Women's age at first marriage?

This analysis cannot answer that. It shows only that the two go together. A link between two country measures, adjusted or not, does not show that either one changes the other. Country figures also say nothing about individual people.

Unemployment vs. Women's age at first marriage

Holds up after adjusting for income

Across 40 countries, Unemployment and Women's age at first marriage rise and fall together at r = +0.33 (on a scale from −1 to +1, where 0 means no link). It holds up almost unchanged when only countries with similar income (GDP per person) are compared (r = +0.43, q = 0.037, allowing for the many pairs tested). Caution: leave-one-out range spans 0.21 in r.

Comparing countries across the middle half of women's age at first marriage, 28.9 to 32 years, unemployment is worse by 0.932% of labor force at the top of that range than the bottom. Comparing only countries with similar national income, the gap is 1.37% of labor force.

How to read these.r runs from −1 (one goes up as the other goes down) to +1 (they rise together), and 0 means no link. Adjusting for national income means comparing countries with the same GDP per person, so differences in wealth can’t explain the link. Income is used in percentage terms, since an extra $1,000 means more to a poor country than to a rich one. p is how likely a link this strong would be if there were really none. Below 0.05 means it is unlikely to be chance. Very small values are written in short form: 1.1e-32 means a decimal point followed by 31 zeros and then 11, so very close to zero. The likely range is where the true figure probably lies, and a range that crosses zero means the link could easily be chance. Countries in the same region tend to resemble each other, so the third figure allows for that, which gives a fairer p. The standard error is the typical size of the error in r. Finally, testing this many pairs means some will look strong by luck alone. A q below 0.05 means this link is unlikely to be one of those.

“Link with income” is how closely each measure tracks GDP per person across countries, from −1 to +1.

Four ways to measure the link

Method	r	p	Countries
Standard (Pearson), not adjusted	+0.327	0.040	40
By rank (Spearman), not adjusted	+0.348	0.028	40
Standard (Pearson), adjusted for national income	+0.428	0.007	40
By rank (Spearman), adjusted for national income	+0.483	0.002	40

The rank version uses only each country’s place in line, from lowest to highest, so a few extreme countries count for less. The adjusted and unadjusted versions use the same 40 countries: those that report both measures and GDP per person. So the gap between them comes from the adjustment, not from a change in which countries are counted. Drop in the size of r after adjusting: -0.101 (a minus sign means it grew).

How solid is it?

Leaving out one country at a time, r ranges from +0.336 (without ESP) to +0.544 (without TUR). The bar above shows that range on a scale from −1 to +1, with the solid line at the full result. The single country that moves r most: TUR (+0.116).

Fragile: this link may not hold up.

Within each region

Countries are not separate, unrelated cases, and neighbors share a lot. A link that holds inside each region is far more believable than one that shows up only when comparing regions.

Europe & Central Asia	30	+0.36

By income third

If the link shows up only in the richest third of countries, it is a feature of rich countries, not a general pattern.

By largest religious group

Countries grouped by a label they share, such as main religion, rather than by a number. Groups of fewer than twelve countries are not shown. These groups differ in income, region and history all at once. So a gap between them is a place to start asking questions, not an answer.

Without outliers (countries far outside the middle half of countries on either measure, by more than one and a half times the width of that middle half): r = +0.428 after dropping 0 countries.

Two series, one country

Both measures over the years for one country you pick. The two charts are stacked so they share only the years along the bottom.

Over time, within countries

Everything above compares countries with each other at one moment. This section compares each country only with itself over 21years. So a link here can’t come from anything about a country that stays the same, such as its history, geography, institutions or culture.

Within countries over time, there is no link that is clearly more than chance (r = +0.113, comparing each country only with itself over the years, and each year only with the same year elsewhere). Whatever the cross-country picture shows, countries whose unemployment moved did not tend to see their women's age at first marriage move with it.

693 country-years (one country in one year), 41 countries, 2001–2021, about 17 years each on average. Share of the variation that happens within countries over time: 28% for Unemployment, 43% for Women's age at first marriage. The margins of error allow for each country appearing many times, and for each year’s value being close to the year before.

Year-to-year changes are a cautious test, not a final answer. Looking only at changes from one year to the next removes each country’s own trends. But it also makes measurement mistakes louder, which pulls the results toward zero. A near-zero result here is weak evidence of no link, not proof.

With one measure years behind the other

Same year (lag 0): +0.113. A peak away from zero does not show which comes first. These series change slowly — this year’s value is close to last year’s. That makes the curve smooth and nearly symmetric, whatever produced the data. Even a sharp peak at one lag (a gap of some years) would not prove that one measure changes the other.

The largest value on this curve (+0.19 at lag +4) is higher than the same-year one by 0.08. That gap is not a finding. It is the largest of 21 closely related estimates, and picking the biggest of many tests always makes it look bigger. That is exactly why nothing on this site is ranked or chosen by lag.

Published from 2001. How many countries report it varies from year to year: 25 in 2012, two in 2021. So the latest value in the time window used is from a different year for different countries. No "better" direction is set.

How this was computed

Data used: most recent value in 2010-2025; values come from 2011–2025. To adjust for income, each measure is first predicted from GDP per person (in percentage terms, on a log scale) with a straight-line fit. Only what is left over is then compared. This is called a partial correlation. The line is drawn the standard way (ordinary least squares), which picks the line that comes closest to all the countries at once. The error margins allow for countries in the same region resembling each other, using 5 World Bank regions. The q-value corrects for testing all 12,497 pairs at once, using the Benjamini–Hochberg method. Underlying data last updated DYB 2024.
