In a municipality located in West Africa with an estimated mid-year population of $250{}000$ , a demographic survey recorded $6{}250$ live births and $2{}500$ deaths within a single year. What is the Rate of Natural Increase (RNI) of this population expressed as a percentage?

Cevap: 1.5 %

Cevap

The Rate of Natural Increase (RNI) of the population is

1.5\%

The Rate of Natural Increase (RNI) measures the surplus of births over deaths in a population over a specific period. Subtracting annual deaths (

2{}500

) from annual live births (

6{}250

) yields a natural increase of

3{}750

. Dividing this increase by the total population (

250{}000

) gives

0.015

, which equals

1.5\%

when multiplied by

100

Adım Adım Çözüm

Calculate the net natural increase in population.

Net natural increase =

3{}750

individuals.

Natural increase measures population growth resulting solely from natural demographic events (live births minus deaths).

Express the natural increase as a percentage of the mid-year population.

RNI =

1.5\%

Dividing the natural increase (

3{}750

) by the total mid-year population (

250{}000

) and multiplying by

100

converts the absolute increase into an annual growth percentage.
