Question

165145In a town, population at the beginning of the year was 40,000 which increasedto 55,000 by the end of the year. In the same year 1350 babies were born and350 people died. Calculate the crude birth rate and the crude death rate ofthe town.In a certain town of the Terai, 750 people were the in-migrants in 2060 B.S.In the same year 350 people migrated to Kathmandu from that town. If themid year population of the town in the same year was 45000 find out the netmigration rate (NMR) and gross migration rate (GMR).The population of any one district of Nepal was 1,50,000 in Rs 2058 B.S. Inthe same year 1000 people moved to other places and 900 came there forsettlement. Now find out the CDR and the GMR.The CBR the CDR and the NMR of Nepal during 2001 A.D. were 33.1,9.6and 4.5 respectively. What would be the rate of natural increase (RNI) andpopulation growth rate (PGR) of Nepal in that year?In one of the villages in Bhojpur, during 2002 A.D., the total number of death​

In one of the villages in Bhojpur, during 2002 A.D., the total number of deaths was 150 and the total number of births was 250. The mid-year population of the village was 10,000. Calculate the crude birth rate (CBR), crude death rate (CDR), and natural increase rate (NIR) of the village.

Options:
A) CBR: 2.5%, CDR: 1.5%, NIR: 1%
B) CBR: 2.5%, CDR: 1.5%, NIR: 0.5%
C) CBR: 2.5%, CDR: 1.5%, NIR: 2%
D) CBR: 2.5%, CDR: 1.5%, NIR: 3%

Answer 1

To determine the net population added per year in a country in the early stages of demographic transition with a crude birth rate of 35 and a crude death rate of 15 per 1,000 people, we subtract the death rate from the birth rate to get 20 per 1,000 people per year, which equals a 2.0% growth rate.

Step-by-step explanation:

In a country at the early stages of demographic transition, if the crude birth rate is 35 per 1,000 people per year and the crude death rate is 15 per 1,000 people per year, the net population growth rate would be the difference between these two figures.

To calculate the net people added to the population, we subtract the death rate from the birth rate: 35 (birth rate) - 15 (death rate) = 20 per 1,000 people per year. This represents the net number of individuals added to the population each year per 1,000 people.

To express this growth in percentage, we simply convert the per 1,000 figure to a percentage by dividing it by 10: 20 per 1,000 is equivalent to a 2.0% growth rate.
