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](https://tex.z-dn.net/?f=365%5Ctimes%2024%5Ctimes%2060%20%3D%20525%2C600%5C%20min)
Birth rate = ![\frac{n}{t} = \frac{4159000}{525600} = 7.913](https://tex.z-dn.net/?f=%5Cfrac%7Bn%7D%7Bt%7D%20%3D%20%5Cfrac%7B4159000%7D%7B525600%7D%20%3D%207.913)
Now,
To calculate the birth rate per thousand people:
= ![\frac{n}{N} = \frac{4159000}{363000} = 11.457](https://tex.z-dn.net/?f=%5Cfrac%7Bn%7D%7BN%7D%20%3D%20%5Cfrac%7B4159000%7D%7B363000%7D%20%3D%2011.457)
