Sources for the data on the International Comparisons table on the Society page.

Every number on table on the Society page is publicly available, usually from multiple sources. Links go to the original data source, where I could find it. Many go to a Wikipedia page with the information. Those pages usually link to the original data sources — and to much more. As few of the links below as possible go to secondary sources like newspaper articles about the original data.

Please let me know if I have made any errors in transferring numbers from the sources to the table above. Also, I am very interested in data that differs from what is above.

mothers – Save the Children’s 20011 Mothers Index (.pdf file). The Best and Worst Places to be a Mother. Helps document conditions for mothers and children in 140 countries – 41 developed nations and 99 in the developing world – and shows where mothers fare best and where they face the greatest hardships. It has three tiers. Our table shows the rank of each country. The closer the rank is to 1, the better for mothers and children.

child well-being – UNICEF’s Child well-being in rich countries. Our table shows the rank of each country. The closer the rank is to 1, the better for children.

From my personal experience, I would add a ninth. Dutch teenagers all have bicycles and think nothing of riding 10 miles to see their friends. They are never dependent on their parents to drive them anywhere in a car.

For the three data points below, you can find basic demographic information at the U.S. Census Bureau’s Information Gateway. Choose your country from the box, and click submit.

  • crude birth rate – The number per 1,000 population.
  • life expectancy at birth. The number of years someone born today can expect to live.
  • under five years old mortality rate. The number per 1,000 births who die before age 5.

maternal mortality – The reports Maternal Mortality: 1990 to 2015 and  Maternal Mortality Estimates (.pdf file) developed by WHO, UNICEF and UNFPA. Maternal mortality ratio. The number of maternal deaths per 100,000 live births.

teenage pregnancies – UN Statistics Division, Prevalence of teenage pregnancy. The table shows the combined number of live births and abortions per 1,000 women 15–19 years old in the years 2005 – 2010.paid maternal leave – Wikipedia’s Parental Leave. Except where specified otherwise, the number of months at 100% pay. Australia offers 18 weeks at the National Minimum Wage. Many of the countries have much longer periods of unpaid leave, sometimes split among the parents. As you can see on the Wikipedia article, the U.S. and the Pacific Island nation of Papua New Guinea are the only two countries in the world that do not offer any paid maternity leave.

unpaid leave – Wikipedia’s Parental Leave. Hardly any countries outside Western Europe have paid paternity leave and not very many more have even unpaid leave. In addition to the paid leave, Australia offers up to 52 weeks unpaid leave shared between the parents. (All leaves need to be taken before the baby’s first birthday.) In the Netherlands, parents can each take 26 unpaid weeks, though they get tax breaks if they do so. In the U.S., parents can take up to 12 weeks each of unpaid leave.
