According to data published by Eurostat, Luxembourg's infant mortality rate has increased from 1.8 to 3.2 per 1000 live births in the last decade.
Meanwhile, the EU-28 has a whole has seen a decrease from 4.4 to 3.6 — while this means that Luxembourg is still below the EU average, no other country has seen an increase as dramatic as Luxembourg's.
Only two other EU countries, Malta and France, saw a slight increase during the same period:
Luxembourg also saw an increase in neonatal mortality (the first 28 days of life) rate between 2008 and 2017, which went form 0.9 to 2.1 per 1000, peaking at 3.1 in 2013.
Late foetal mortality (still births) also increased in the same period, from 3.7 to 6.0, as did the perinatal mortality (still births and deaths of children under one week) rate which increased from 4.3 to 8.1. Perinatal mortality rates were at the highest in the period in 2015, at 9.6.
Eurostat do not offer EU-28 averages for these statistics, but as a means of comparison Germany's perinatal mortality rate has been steady at around 5.4, while the UK's went from 7.5 in 2008 to 6.3 in 2017. The same countries had late foetal mortality rates of around 3.5 and 4.6 for most of the period.
