4.4 The migration balance
Altogether,  the  ALCS  2013-14  suggest  that  some  3.0  million  of  the  resident  population  ever  migrated, either internally between provinces or across international borders. This number represents 11 percent of
the total population. Together these migrants moved some 4.8 million times. The reason for migration that was most reported
– for 40 percent of migrations – was moving because the parents or family moved. This high proportion is not surprising given the large number of
– dependent – children in Afghan families. The second main reason mentioned was return from displacement 25 percent,
followed by employment-related reasons 13 percent. Assuming that dependents who moved because their families  moved  can  be  redistributed  to  the  primary  reasons  of  those  families,  the  displacement  return
category would actually be 42 percent of migration motives. Together with 10 percent moves that were caused by violence or conflict, this means that more than half of the moves that Afghan people made were
related to violence-related displacement. Looking for work would be the second main reason for changing the  place  of residence 22 percent  of the  migrations.  Although  marriage  is  a  very  important  reason  for
changing  the  place  of  residence,  especially  for  women,  at  the  level  of  international  and  inter-province migration, this is only a minor reason. Most of marriage-related moves occur within the province CSO
2014. The  combined  effect  of  internal  migration  and  immigration  on  the  populations  in  the  provinces  of
Afghanistan is presented in
Figure 4.14
. It clearly shows the migration system of Kabul and its immediate surrounding provinces as, respectively, absorber and suppliers of internal migrants. Also provinces along
the  borders  of  Pakistan  and  Iran,  and  those  with  large  urban  centres  prominently  figure  as  areas  with population gains from either immigration or internal migration.

Excluding emigrants currently living abroad.
The net relative impact of migration was largest in Kabul and Nimroz, where the population grew with around one quarter due to the difference between people entering and leaving. Balkh followed at  a third
place with a net gain of just below 10 percent. Pansjher is the province that lost relatively most population: it would have had 28 percent more population without migration. Parwan, Logar, Wardak and Laghman
would have had between 10 and 19 percent more people. In absolute numbers, Kabul had by far the largest net gain due to migration: close to 900 thousand people.
Also Balkh, Herat and Nangarhar had substantial net migration gains of around 100 thousand persons each, while Khost, Kunduz Nimroz and Kunhara had between 30 thousand and 50 thousand more people coming
in  than  going  out.  On  the  other  hand,  Laghman  and  Wardak  had  a  net  loss  of  well  over  100  thousand population each, and Parwan and Logar between 80 and 90 thousand.
To the extent that the assumptions for the calculation of the annual immigration and emigration rate are valid sections 4.3.1 and 4.3.2, respectively, the annual population loss in the two years before the survey
would be 105 thousand persons. This corresponds with a negative annual migration rate of 0.4 percent.
