Updates

Methodological update: added example of Hinduism in the USA and the methodology of the International Religious Demography Data Quality Index.
For the first time, the Hindu religion is broken down into its major traditions with best estimates by country of the numbers of Vaishnavites, Shaivites and Saktists. See the Hindu specific queries on Religious Traditions page.

For example, the Global 24-hour change query shows that every day on average over the last 10 years the global Christian population increased by 79,000 people and the Muslim population increased by 78,000 people. The 24-hour change at the end of the period, in 2015, is even higher: 88,000 Christians and 84,000 Muslims.
New queries on the "Religion" page report the 24-hour population change by religion in each country and region and globally.
