RRB Staff Nurse Previous Year Paper [Held on 20 July 2019 (Shift II)]

Deaths in January x 12/mid-year population x 100
No of deaths during the year/mid-year population x 1000
Total No of deaths due to a particular disease/Total no of cases due to same disease x 100
No of deaths from the specific disease in a year/total deaths from all causes in that year x 100

Answer 1

Explanation:

D=total number of deaths registered during the calendar year
P= total mid-year estimated population or the total population of the middle of the year
K=a constant usually taken as1,000

Key Points

Natural population growth happens because of the following
1. Birth Rate
2. Death Rate
The natural increase in birth rate and death rate causes natural population growth.
Basic components of population change-
- The fertility rate in women
- Mortality
- Migration
Natural increase is the difference between the no. of births and deaths in the population.
Crude Birth Rate - It is the total number of live births per 1,000 population divided by the length of the period in years.
- current rate - 18.2births/1000
Crude Death Rate - the ratio of deaths to the population of a particular area or during a particular period of time, usually calculated as the number of deaths per one thousand people per year.
