The region of Sub-Saharan Africa has the highest birth rate in the world. As of 2016, Niger, Mali, Uganda, Zambia, and Burundi have the highest birth rates in the world. This is part of the fertility-income paradox, as these countries are very poor, and it may seem counter-intuitive for families there to have so many children. The inverse relationship between income and fertility has been termed a "demographic-economic "paradox"" by the notion that greater means would enable the production of more offspring as suggested by the influential Thomas Malthus.

In 2013, the lowest birth rates were reported in the Northeast, while the highest rates were located in the south east. For example, a 2001 study by UNICEF found that the US teenage birth rate was the highest among 28 OECD nations in the review; in a 1999 comparison by the Guttmacher Institute, U.S. teen pregnancy and teen birth rates were the second-highest among the 46 developed countries studied. In 2002, the U.S. was rated 84th out of 170 World Health Organization member countries based on teenage fertility rate.

Afghanistan has the 11th highest birth rate in the world, and also the highest birth rate of any non-African country (as of 2016). The rapid population growth of Afghanistan is considered a problem by preventing population stabilization, and affecting maternal and infant health. Reasons for large families include tradition, religion, the low status of women and the cultural desire to have several sons.

There is much variation regarding birth weight within continents, countries, and cities. Even though over 20 million babies are born each year with low birth weight, it is hard to know the exact number as more than half of babies born in the world are not weighed at birth. The baby’s weight is an indicator of the mother and babies health. In 2013 22 million newborns had low birth weight, around 16 percent of all babies globally. Data on low birth weight is adjusted to account for under reporting. South Asia has the highest rate of babies not weighted at birth with 66 percent, but also have the highest low birth weight at 28 percent worldwide. West and Central Africa and least developed countries are next with 14 percent low birth weight worldwide.

Birth rates vary even within the same geographic areas. In Europe, as of July 2011, Ireland's birth rate is 16.5 per cent, which is 3.5 per cent higher than the next-ranked country, the UK. France has a birth rate of 12.8 per cent while Sweden is at 12.3 per cent. In July 2011, the UK's Office for National Statistics (ONS) announced a 2.4% increase in live births in the UK in 2010 alone. This is the highest birth rate in the UK in 40 years. By contrast, the birth rate in Germany is only 8.3 per 1,000, which is so low that both the UK and France, which have significantly smaller populations, produced more births in 2010. Birth rates also vary within the same geographic area, based on different demographic groups. For example, in April 2011, the U.S. CDC announced that the birth rate for women over the age of 40 in the U.S. rose between 2007 and 2009, while it fell among every other age group during the same time span. In August 2011, Taiwan's government announced that its birth rate declined in the previous year, despite the fact that it implemented a host of approaches to encourage its citizens to have babies.

West/Central Africa has the highest rate of children under five underweight in the world. Of the countries in this region, the Congo has the lowest rate at 14%, while the nations of Democratic Republic of the Congo, Ghana, Guinea, Mali, Nigeria, Senegal and Togo are improving slowly. In Gambia, rates decreased from 26% to 17% in four years, and their coverage of vitamin A supplementation reaches 91% of vulnerable populations. This region has the next highest proportion of wasted children, with 10% of the population under five not at optimal weight. Little improvement has been made between the years of 1990 and 2004 in reducing the rates of underweight children under five, whose rate stayed approximately the same. Sierra Leone has the highest child under five mortality rate in the world, due predominantly to its extreme infant mortality rate, at 238 deaths per 1000 live births. Other contributing factors include the high rate of low birthweight children (23%) and low levels of exclusive breast feeding (4%). Anemia is prevalent in these nations, with unacceptable rates of iron deficient anemia. The nutritional status of children is further indicated by its high rate of child wasting - 10%. Wasting is a significant problem in Sahelian countries – Burkina Faso, Chad, Mali, Mauritania and Niger – where rates fall between 11% and 19% of under fives, affecting more than 1 million children.
