Birth registration vs. Women in management
Holds up after adjusting for income
Across 140 countries, Birth registration and Women in management 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 = +0.21, q = 0.045, allowing for the many pairs tested). Caution: direction is not consistent across regions.
Comparing countries across the middle half of women in management, 25.6% to 39.8% of managers, birth registration is better by 9.54% of children under 5 at the top of that range than the bottom. Comparing only countries with similar national income, the gap is 4.68% of children under 5.
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 | 8.1e-5 | 140 |
| By rank (Spearman), not adjusted | +0.255 | 0.002 | 140 |
| Standard (Pearson), adjusted for national income | +0.209 | 0.014 | 140 |
| By rank (Spearman), adjusted for national income | +0.002 | 0.982 | 140 |
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 140 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: +0.118 (a minus sign means it grew).
How solid is it?
Leaving out one country at a time, r ranges from +0.177 (without STP) to +0.231 (without MLI). 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: STP (-0.031).
- direction is not consistent across regions
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.
| n | r | ||
|---|---|---|---|
| East Asia & Pacific | 23 | +0.37 | |
| Europe & Central Asia | 42 | +0.46 | |
| Latin America & Caribbean | 22 | -0.09 | |
| Middle East, North Africa, Afghanistan & Pakistan | 12 | +0.54 | |

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.

| Poorest third | 47 | +0.18 | |
| Middle third | 46 | +0.23 | |
| Richest third | 47 | -0.35 |
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.

Over time, within countries
Everything above compares countries with each other at one moment. This section compares each country only with itself over 0years. So a link here can’t come from anything about a country that stays the same, such as its history, geography, institutions or culture.
Not enough history inside each country to look at this over time. That needs countries measured for several years in a row, and at least one of these measures is measured too rarely.

How this was computed
Data used: most recent value in 2010-2025; values come from 2010–2025. 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 7 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.

This page shows that two measures go together. It does not show that Birth registration changes Women in management, or the reverse. These figures also describe countries, not individual people. See the ecological fallacy.
