Question

In Gorkha 2003 the initial population was 37000 and final population was 49000 and population doubling time was 70 years. If 5000 death,6ooo in - migrants and 5000 out migrants were recorded in that year then find CBR ​

Answer 1

102.95

Step-by-step explanation:

first take out the mid year pop which will be,

(initial pop + final pop)/2 = 43000

next we will take out PGR,

PDT= 70/PGR so,

PGR= 70/PDT= 70/70=1 percent

now calculate CDR

CDR= (5000/43000) × 1000= 116.2 per thousand

again,

NMR = {(6000-5000)/43000}×1000= 23.25 per thousand

now we have,

PGR= {(CBR-CDR+NMR)/1000}× 100

CBR= {(PGR× 1000)/100} - NMR +CDR

CBR = 102.95
