what information can be gained from the country having high crude birth rate
Answers
Answer:
The crude birth rate in a period is the total number of live births per 1,000 population divided by the length of the period in years.[1] The number of live births is normally taken from a universal registration system for births; population counts from a census, and estimation through specialized demographic techniques[clarification needed]. The birth rate (along with mortality and migration rates) is used to calculate population growth. The estimated average population may be taken as the mid-year population.[2][3]
Another term used interchangeably with birth rate is natality.[4]
When the crude death rate is subtracted from the crude birth rate, the result is the rate of natural increase (RNI).[5] This is equal to the rate of population change (excluding migration).[5]
The total (crude) birth rate (which includes all births)—typically indicated as births per 1,000 population—is distinguished from a set of age-specific rates (the number of births per 1,000 persons, or more usually 1,000 females, in each age group).[6] The first known use of the term "birth rate" in English was in 1859.[7]

The average global birth rate was 18.5 births per 1,000 total population in 2016.[9] The death rate was 7.8 per 1,000. The RNI was thus 1.6 percent. In 2012 the average global birth rate was 19.611 according to the World Bank[10] and 19.15 births per 1,000 total population according to the CIA,[11] compared to 20.09 per 1,000 total population in 2007.[12]
The 2016 average of 18.6 births per 1,000 total population equates to approximately 4.3 births per second or about 256 births per minute for the world.
