Question

In​ 2015, there were approximately 4 comma 159 comma 000 births in a country. Find the birth rate in births per minute. Assuming a population of 363 ​million, what was the annual birth rate in units of births per 1000​ people?

Answer 1

Birth rate per minute is 7.913

Birth rate per thousand is 11.457

Solution:

As per the given data in the question:

No. of births in the year 2015, n = 4,159,000

Total population size, N = 3,630,00,000 = 363000 thousand

Now,

To calculate the birth rate in births per min:

No. of days in the year 2015 = 365 days

No. hours in a day = 24 hrs

1 hour = 60 mins

Thus

Total minutes in the year 2015, t =
`365* 24* 60 = 525,600\ min`

Birth rate =
`(n)/(t) = (4159000)/(525600) = 7.913`

Now,

To calculate the birth rate per thousand people:

=
`(n)/(N) = (4159000)/(363000) = 11.457`
