• TMIDPS is designed to make inferences on
  migration and internally displaced people in
  Turkey.
• Since the survey especially focuses on IDPs, it
  is appropriate to divide the survey population
  into two main strata.

3
2 main strata

• The first of these strata, which can be named as
  Out-migrant provinces is composed of 14
  provinces which experienced dense internally
  displacement
• The second of that in-migrant provinces which
  have dense immigration from 14 provinces

4
2 main strata

• In-migrant provinces stratum will be
  constructed by using the information which can be
  obtained from previous population censuses. These
  information will be formed by cross-tabulation of
  the variables residence for 5 years before the
  census day and place of birth with place in
  census day
• Out-migrant provinces consists of following 14
  provinces in East and South-east Anatolia regions
  (Adiyaman, Agri, Batman, Bingöl, Bitlis,
  Diyarbakir, Elazig, Hakkari, Mardin, Mus, Siirt,
  Sirnak, Tunceli ve Van).

TMIDPS stratification

• The sample size of TMIDPS requires different
  calculations due to its design approach. In other
  words, total sample size will be the sum of each
  stratum
• Stratification will be as follows
• Stratum 1 In-migrant provinces- Dense districts
  (if possible, quarters) stratum
• Stratum 2 Out-migrant provinces - Urban stratum
• Stratum 3 Out-migrant provinces Rural-
  excluding returned villages stratum
• Stratum 4 Out-migrant provinces Returned
  villages stratum

Sampling and listing implementation and sample
sizes in strata

• Stratum 1 In-migrant provinces- Dense districts
  (quarters) stratum This stratum will be formed
  by means of migration information comes from SIS
  with maximum detail (if possible quarter level,
  if not district level), Then sample blocks, which
  are selected by probabilistic and random
  procedure, will be screened by a short
  questionnaire in order to determine the crude
  migration level of households. Then, the detailed
  household interviews will be conducted in second
  stage. This is a two-phase sampling selection
  operation. A 1000 HH interviews is planned to
  conduct.

Sampling and listing implementation and sample
sizes in strata

• Stratum 2 Out-migrant provinces - Urban
  Household interviews will be conducted from the
  probabilistically and randomly selected blocks of
  urban stratum which is formed by means of
  structure enumariton schedules provided by SIS
  for 14 provinces. It is planned to conduct 1500
  household interviews.

Sampling and listing implementation and sample
sizes in strata

• Stratum 3 Out-migrant provinces
  Rural-excluding for returned villages stratum
  Within 14 provinces and excluding returned
  villages, households will be selected from
  probabilistically and randomly selected blocks of
  municipals or villages. It is planned to conduct
  1500 household interviews.

11
Sampling and listing implementation and sample
sizes in strata

• Stratum 4 Out-migrant provinces Returned
  villages stratum Households will be selected
  probabilistically and randomly from the returned
  villages. It is planned to conduct 500 household
  interviews.
