Using Data from the Demographic and Health Surveys the authors examine the stalling of the fertility decline in four countries of Eastern Africa. They found that fertility has remained at pre-transition level in Uganda over the past 20 years. In both Kenya and Tanzania the fertility decline has stalled at the national level. In Zimbabwe fertility declined slightly at the national level, but the decline has stalled in some regions.
The results suggest that declines in contraceptive use, increasing preferences for larger families, and increases in adolescent fertility were consistently associated with stalls in fertility across all four countries.

The author analyzes why the fertility transition in Sub-Saharan Africa occurred later and is proceeding at a slower pace. He concludes that several factors contribute to the slow pace:
(1) delayed and slower (economic) development,
(2) pro-natalist nature of African societies; and
(3) weakness of family planning programs in Africa.

In a recent research project the Pew Research Center projected Muslims to be the world’s fastest-growing major religious group in the decades ahead. In less than 20 years from now, the number of babies born to Muslims is expected to exceed births to Christians.

Across Europe birth rates are tumbling. The net effect is a ‘perfect demographic storm’ that will imperil economic growth across the continent.
The EU’s Eurostat agency estimates that by 2050, Portugal will be the country in Europe that is home to the smallest proportion of children, with just 11.5% of the population expected to be under the age of 15.

The German Statistics Office has released a report negating hopes that the refugee crisis might actually help the country's demographic decline. The country would have to allow around half a million immigrants every year.

South Korea’s low birth rate means the size of its youth population – those aged between nine and 24 – will be slashed in half by 2060

After abolishing the one-child policy, Communist party mulls financial incentives to parents who have more than one baby.
China’s birth rate, one of the world’s lowest, is fast becoming a worry for authorities rather than the achievement it was considered at a time when the government feared over-population.

Evidence from India’s last Census in 2011, confirmed by data from the recent National Family Health Survey 2017 (NFHS-4), shows that fertility in India is fast approaching replacement levels.
But even after fertility rates drop to replacement levels, the total population will still grow, and is likely to reach 1.7 billion by 2050.

As of 2010, there were 4.8 million Muslims in Germany (5.8% of the country’s population) and 4.7 million Muslims in France (7.5%). In Europe overall, however, Russia’s population of 14 million Muslims (10%) is the largest on the continent.
