TURKISH STATISTICAL INSTITUTE Demography Statistics Department Population and Migration Statistics Group HISTORY OF POPULATION CENSUSES IN TURKEY 8

TURKISH STATISTICAL INSTITUTE Demography Statistics Department Population and Migration Statistics Group Population Censuses in Turkey History  first census in 1927,  second census in 1935,  every five years between ,  last traditional census in 2000 Totally 14 traditional population censuses. Method  Traditional census method (face to face interview),  Standard questionnaire,  De facto population census definition,  One day application with national curfew (no permission go out). 9

TURKISH STATISTICAL INSTITUTE Demography Statistics Department Population and Migration Statistics Group Population Censuses in Turkey Main Problems  No information on usual residence (de jure),  Over-counting (imaginary) population,  High cost  Duration of data processing around 3.5 years,  Restricted questions because of the one-day application,  Information on population size and their characteristics available within ten-year interval. 10

TURKISH STATISTICAL INSTITUTE Demography Statistics Department Population and Migration Statistics Group Target Changing the system from traditional census to register-based census Establishing an address based population registration system and changing the census methodology from traditional to register based. 11

TURKISH STATISTICAL INSTITUTE Demography Statistics Department Population and Migration Statistics Group ADDRESS BASED POPULATION REGISTRATION SYSTEM (ABPRS) 12

TURKISH STATISTICAL INSTITUTE Demography Statistics Department Population and Migration Statistics Group Purposes of the ABPRS  To define an address standard  Standardized numbering and signboarding  Central address database (NAD)  full coverage…  Covering all people  place of residence… 13

TURKISH STATISTICAL INSTITUTE Demography Statistics Department Population and Migration Statistics Group Address MERNIS-Personal Information ABPRS WHAT IS ADDRESS BASED POPULATION REGISTRATION SYSTEM? MATCHED * personal information from MERNIS * addresses from NAD (By TR-ID numbers) Unique code was given to each address. 14

TURKISH STATISTICAL INSTITUTE Demography Statistics Department Population and Migration Statistics Group 2011 Population And Housing Census  Turkey has conducted a census in 2011 in the scope of the 2010 World Population and Housing Census Programme.  In this round, Turkey changed the (traditional) census methodology, and at first time;  used the population registers,  applied a census according to the de jure population definition,  conducted a census with the 2-3 month field application instead of one-day application. 19

TURKISH STATISTICAL INSTITUTE Demography Statistics Department Population and Migration Statistics Group Purpose To obtain information that are not available in the ABPRS and other administrative registers or can not obtained from regular household surveys in province and district level. Such as labor force, characteristics of buildings and dwellings, migration characteristics, etc. Legal base The Official Statistics Program of TurkStat, and in line with EU Requirements Why did we need a census ? 20

TURKISH STATISTICAL INSTITUTE Demography Statistics Department Population and Migration Statistics Group Methodology of the Census  Combined method; by using population registers and by conducting register based large-scaled sampling survey  In the design of the census, registers were used priorly;  to obtain population count and age-sex distribution of the population,  to construct an address frame 21

TURKISH STATISTICAL INSTITUTE Demography Statistics Department Population and Migration Statistics Group Scope of the 2011 PHC  Register based large-scaled sampling survey  For households, enumeration areas were selected (11,7%) as sample of the study, from enumeration areas in total.  Complete enumeration of institutional places  Turkish Citizens and foreigners living in the country were covered.  Foreigners found in the country for less than 6 months during the field application and Turkish Citizens living abroad were not covered. 23

TURKISH STATISTICAL INSTITUTE Demography Statistics Department Population and Migration Statistics Group  The number of field staff was less than Advantages in terms of budget, quality of staff, controlling the field operation and logistics.  Netbook usage(CAPI) cross checks between answers at the time of interview increased data quality  Netbook usage time efficiency  By the online data transfer enumerators sent data to the main system, field application can be monitored daily through central web based system Advantages of the Methodology 25

TURKISH STATISTICAL INSTITUTE Demography Statistics Department Population and Migration Statistics Group  The first time to use this methodology: a challenge in terms of lacking of experience  Data collection period is quite long (2-3 months): the gap between the reference date increased  Finding the addresses in the field: still a problem that NAD is not updated regularly by the municipalities Disadvantages of the Methodology 26

TURKISH STATISTICAL INSTITUTE Demography Statistics Department Population and Migration Statistics Group 2011 PHC Questionnaire was prepared considering:  UNECE Recommendations  EUROSTAT Regulations  National needs  Previous censuses (as possible to ensure the comparability)  Results of pre-tests and pilot studies (learnt lessons from preparatory works regarding the efficiency and applicability of questions) How Content of the 2011 PHC Questionnaire was Generated? 27

TURKISH STATISTICAL INSTITUTE Demography Statistics Department Population and Migration Statistics Group TARGETS FOR THE NEXT CENSUS 31

TURKISH STATISTICAL INSTITUTE Demography Statistics Department Population and Migration Statistics Group Main goal is changing the system from combined method to completely register based census. But until achieving this goal we intent to:  Improve the system by using more registers than 2011 PHC (both for quality cheques and directly producing statistics)  Make use of GIS technologies  Using data of regular household surveys by combining them with related registers  Preparations for the next round has been started in Targets 32
