• Human migration is the movement by people
from one place to another with the intentions
of settling, permanently or temporarily in a
new location.
• The causes of migration may be economical,
social, political, environmental, war and
violence.
• Both positive and negative effects of migration
can be seen.

6. CONTD…
• Estimation of Intercensal migration rate can be
calculated both by national growth rate method
and Vital statistics method.
• Since the vital statistics of our country is weak. So
we have to use national growth rate method.
• Net migration rate is the difference between total
number of immigrants/in-migrants and
emigrants/out-migrants in a country during a
year per 1000 of the mid year population.

7. OBJECTIVES
• To know the Intercensal migration rate of
Bardiya district.

8. METHODOLOGY
• Secondary data's from Census reports.

9. FINDINGS
Population of the Bardiya district of the latter
census year 2011 (P'i) = 4,26,576
Population of the Bardiya district of the earlier
census year 2001 (p°i) = 3,82,649
Population of the nation of the latter census
year 2011 (P'T) = 26494504
Population of the nation of the earlier census
year 2001 (P°T) = 23151423
Net Migration rate for Bardiya district (bi) = ?

10. CONTD…
Now,
bi = [( p'i - p°i/ p°i) - ( p't - p°t/p°t)] × k
bi = [(426576
- 382649 /382649) - (26494504-
23151423/23151423)] × 1000
bi =[( 0.114) - (0.144)] × 1000
bi = - 0.03 × 1000
bi = -30

11. CONCLUSION
• The negative value of bi indicates the net out
migration. So, Bardiya district has 30 net out
migrants.
