    What is Demography?

    • Two words in Ancient Greek: Demos (people, society) and Grafos (writing, drawing, description)
    • Defined as the study of the structure, characteristics, and changes of the population within a geographic area.
    • First used by Belgian statistician Achille Guillard in 1855.

    What is Population?

    • The total number of individuals living in a specific area at a specific time.
    • Is dynamic (constantly changing due to time and space).

    Population Components

    • Birth
    • Death
    • Migration

    Basic Demographic Equation:

    • Starting Population + Births - Deaths + Internal Migration - External Migration = Population

    What Does Demography Research?

    • Numerical size of population
    • Population distribution (geographical)
    • Population structure (gender, education, age)
    • Population change
    • Population processes (birth, death, migration effects)

    What Does Demography Examine?

    • Numerical changes in population
    • Determinants, results, and differentiation of the changes

    Demography (Technical-Formal vs Economic-Social)

    • Technical-Formal: collection and analysis of demographic data, creating demographic indicators, examining relationships
    • Economic-Social (Population Research): demographic phenomena, social, economic, political, biological, cultural factors

    Why is Demographics Important?

    • Population change impacts social, economic, and technical changes.
    • Influences various areas (policy, social planning, business life, global/regional/local planning human resources).

    Demography and Other Disciplines

    • Demography incorporates approaches, concepts, and theories from other disciplines (economics, sociology, ecology, geography, genetics, statistics, nutrition).

    Data Sources in Demography

    • Population Censuses
    • Population Registration Systems (birth, death, marriage, divorce)
    • Demographic Research
    • Regional/Local Research on Society
    • Sampling Techniques (e.g., TNSA)

    Population Censuses

    • Ancient practice (Egypt, China, Rome, Palestine).
    • Used for military, population, labor force, and taxes.
    • Historically, women and children often not counted.
    • Modern censuses (Sweden 1749, USA 1790, France/England 1801)
    • Importance increased under UN guidance (world population counted over time).
    • Now nearly universal.

    Censuses Historically (Turkey)

    • First census mentioned biblically.
    • Turkish censuses (often every 5 years, now every 10 years)
    • Address-Based Population Registration System (ADNKS)
    • Conducted by TUIK.

    Why is the Census Important?

    • Critical data source for the entire country's population.
    • Determines resources allocation for local governments.
    • Used to create voter lists.
    • Creates the sampling frame for research.

    Problems with the Census

    • Reaction to the census
    • Errors (undercount/overcount, qualitatively, reporting, data transfer bias)
    • High cost from large population size

    Recording Systems

    • Main reason: fulfilling legal rights, issue identity cards, formalizing parents, owning property, education opportunities, right to travel
    • Vital Records (birth, death, marriage, migration, divorce)
    • Partial Records (Social Security Institution etc.)
    • Constant information collection, converted to statistics, up-to-date records for individuals.

    Recording System (details)

    • Separate records for each individual
    • Covering everyone within limits
    • Time between event and recording is short.
    • Results presented regularly

    Registration System in Turkey

    • MERNİS since 2022 (Ministry of Interior, population, citizenship affairs)
    • Computerization of population records, identity numbers
    • Online information exchange between government agencies
    • Address Based Population Registration System (ADNKS)
    • TÜİK responsible for assigning people to addresses.
    • Ministry of Interior, Ministry of Foreign Affairs, Ministry of Labor, UN offices, related directorates
    • Marriage/Divorce Records managed by TÜİK

    Problems with the Census Research

    • Ignoring groups (incompleteness)
    • Underreporting (in rural areas)
    • Gender bias
    • Inadequate/unorganized migration statistics

    Researches (overview)

    • More questions, information from different periods, focused on a selected population sample, in-depth and quality information. Smaller scale than census studies (lower cost).

    Research Methods

    • Qualitative research (not based on numbers/measurement, aims to understand experiences, feelings, thoughts, answers to the 'how' question).
    • Quantitative research (most widely used to answer how much/many questions, uses numbers/measurement, uses sampling, representative nature).

    Research Types

    • Cross-sectional research (interviewing individuals at a designated time).
    • Longitudinal research (follow-up of individuals over time).
    • Retrospective research (examining past experiences of individuals).

    Demographic Research in the World

    • Knowledge, Attitude, and Practice (KAP) surveys
    • World Fertility Surveys
    • Demographic and Health Surveys
    • Family and Fertility Surveys
    • Gender and Generations Surveys

    Demographic Research in Turkey

    • TÜİK and Hacettepe University Population Research Institute.
    • Turkey Population Survey (1965-1968), most comprehensive.
    • Hıfzı Sıhha Genel Müdürlüğü
    • Every five years from HÜNEE (since 1968, including Family Structure, Fertility, Health Surveys).

    Problems for Research

    • Poor data quality (sampling errors, data collection, interview bias, respondent bias, field conditions, data entry/analysis errors)
    • Analysis related errors

    Comparison of Demographic Data Sources

    • Censuses: Information for every individual, but may lack current information, prone to sampling errors, high cost
    • Recording Systems: Current information, less prone to sampling errors, but may not have info for every individual, lower cost
    • Research: More information, but may have sampling errors, lower cost, usually focused on a selected population sample.
