According to UNICEF (December 2013), approximately how many babies are born in the world each day?

It is difficult to come to the exact number of births every day since not all births are registered or recorded.

The UNICEF estimates that an average of 353,000 babies are born each day around the world. The crude birth rate is 18.9 births per 1,000 population or 255 births globally per minute or 4.3 births every second (as of Dec. 2013 estimate)

Our current world population is approximately 7.2 billion and growing. It passed the 7 billion mark in 2011. It is expected to reach between 8 to 10 billion by 2050.

Advances in medicine and the industrial revolution were the catalysts to the population boom. There are fewer deaths now and babies have bigger chances of living their full lives and having children of their own. We have access to clean water and this lowered the incidence of life threating diseases like Malaria.
