More than half the countries of the world have a majority who identify themselves as members of a Christian sect. However, in some countries many or most of these are non-practicing Christians.

No country has a majority of people identified as having no religion, even though non-religious people account for close to a billion people worldwide.

According to the website Religious Tolerance.org , the five largest religions in the world are: Christianity, with 2.015 billion adherents; Islam, with 1.215 billion; no religion, with 925 million; Hinduism, with 786 million; and Buddhism, with 362 million. Combined, these five religious groups account for 87 percent of the world’s population.

• Congenital malformations, deformations and chromosomal abnormalities. These account for 20 percent of cases
• Disorders related to short gestation and low birth weight alone account for 16 percent of cases
• SIDS (Sudden Infant Death Syndrome) which accounts for 8
  percent.

All of these occur more often when maternal health and nutrition are poor. In many cases, causes are multiple with low birth weight being a major factor.

Infant mortality is highest in developing nations. These countries generally have a low href=/graph/eco_gdp>GDP, low literacy,
high levels of poverty, a high rate of maternal mortality and a high number of children per woman.

To get an idea of how many marriages end in divorce, take a look at the number of divorces per 100 marriages, where Belgium tops the list at 59.8 divorces for every 100 marriages.

Only six countries are in the top 20 of both divorces per 1000 people and divorces per 100 marriages.

The United States and Russia are first and third, respectively, for divorce rates per 1000 people. But they are first and second in the number or marriages per 1000 people per year, and don’t appear in the top 20 of divorces per 1000 marriages.
