Types of migration

Answer 2

Internal migration: in-migration and out-migration

International migration: immigration and emigration

Question 3

In-migration & out-migration

Answer 3

(IM/P) *k, where:

IM = # people moving in a given year
P = total mid-year population
k = constant

OM = # people moving out in a given year

Question 4

Age-specific migration rate

(# migrants aged x at end of year) / (end of year population aged x) *k

Question 6

Forward survival method

Answer 6

Estimated net migration = Pn - P0x *S, where:

Pn = end of period population aged x+n
P0x = initial population aged x
S = survival rates from age x to age x+n
n = interval

Question 7

Residual methodology to compute undocumented immigrants

Answer 7

Utotal = Atotal - Ltotal, where:

Utotal = total unathorized immigrants
Atotal = total immigrants (legal and unauthorized)
Ltotal = total legal immigrants
