The Baltic countries lost a quarter of their population between 1990 and 2020. While net migration was the main driver, below-replacement fertility reduced their populations by about one tenth.

Sex ratio at birth hit a new record last year in Hungary.
The number of newborn boys per 100 girls jumped above 107. While boys are the majority at birth, their share gradually declines, by the time people reach their 50s, women become the majority.

One in five people eligible to vote in next year’s Hungarian election was too young to vote in 2010. Nearly 2 million people have died since then, leading to a 20% turnover in the voting-age population between 2010 and 2026.

The young age profile fully offset population losses from negative migration in Central and Eastern Europe between 1990 and 2020. Population Council just featured my Population and Development Review paper in a short summary!

South Korea’s dramatic fertility decline over the past 25 years has been driven mainly by falling birth rates among women aged 25–29. Since 2012, fertility among those aged 30–34 has also dropped sharply.

Yes, exactly! :)

The age pattern of divorce among men has flattened over the past 25 years. Around the millennium, the risk of divorce fell sharply with age; today in Hungary, it’s nearly the same from 25 to 55. The same pattern holds for women.

📢My paper is out in Population and Development Review.😀Central and Eastern Europe’s population change isn’t just about fertility, mortality, and migration — the age structure also an important factor.

White and Black Americans are hit harder by the US opioid crisis than Hispanics. In 2023, overdoses claimed 107,000 lives, over 75% tied to opioids. A new study says the surge is mainly supply-driven.

Over the last two decades, Romania, Czechia and Slovakia cut their life expectancy gap with the EU27. But Hungary, Poland and Bulgaria remain stuck — showing little convergence.

Great honour to present my research at the Annual Conference of the British Society for Population Studies in Swansea — in the session with the undeniably sexy name: Innovations in Formal and Mathematical Demography. 🤓

Fertility boom in Kazakhstan should receive more attention: TFR increased from 1.9 to 3.3 over two decades. This seems to be an example of a reversed fertility transition, with rising progressions to higher-order births and little fertility postponement.

Below-replacement fertility can have very different outcomes. With a TFR of about 1 (as in China or Malta), the third generation is only one-quarter the size of the first. With a TFR of about 1.7 (as in Bulgaria or Romania), it is three-quarters the size.

Hungary’s fertility rate fell below 1.3 in the first half of the year. Combined with a shrinking reproductive-age population, this led to 10,000 fewer births compared to 2021.

More men died from COVID-19, but since men generally have a higher risk of death at all ages, women weren’t always better off when looking at the increase in mortality. In some cases, their death rates rose even more. Excellent new study just out!

The fertility gap between graduate and non-graduate women becomes statistically insignificant when accounting for first-in-family (FiF) status. FiF graduates have fewer children than both non-FiF graduates and non-graduates.

Life expectancy gains have slowed sharply in the past decade in Western Europe. The increase was just 1.1 years, less than half the progress seen in earlier decades.

Romania’s population dropped from 23.2M to 19.3M between 1990 and 2020. The decline was driven by net out-migration and low fertility, partly offset by a relatively young age structure and rising life expectancy.

Fertility in the EU27 fell to a historic low below 1.4 in 2023. The TFR of 1.38 marks a 0.15-point drop in just two years.

Malta is losing its women. In just 10 years, the number of women per 100 men plunged from 100 to 89 — a unique demographic shift in Europe.

No kids without moving out? Or why move out without kids? Fertility rates are lower in countries where more young adults (20–29) still live with their parents.
