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

Answer:

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 = $365\times 24\times 60 = 525,600\ min$

Birth rate = $\frac{n}{t} = \frac{4159000}{525600} = 7.913$

Now,

To calculate the birth rate per thousand people:

= $\frac{n}{N} = \frac{4159000}{363000} = 11.457$
