Consider the following statements :
1. This is the first time since independence that the decadal growth rate of population has declined.
2. Workers (in census 2011) are those who have worked for atleast one day during the reference year.
Which of the statements given above is/are correct ?

1 only
2 only
Both 1 and 2
Neither 1 nor 2
Explanation:
Now most people would think that our population growth rate has started declining recently and so statement 1 might be correct. However, the fact is the decadal growth rate saw a decline first in 1981 after independence. This is the 4th time we are witnessing a decline. Statement 2 looks ridiculous and on first reading it appears wrong. But it is correct. This is what the census uses as its definition – Workers are those who have worked for atleast one day during the reference year. So, a surprising statement and hence important for UPSC exams.
