What is the scope and objective of this Demographic Surveys course?
This Master's level course introduces demographic surveys, blending theoretical rigor with practical application in developing countries like Haiti and the Caribbean. It aims to equip students with skills for valid quantitative inferences from sampled data, covering the entire survey lifecycle from design to reporting. The 15-hour curriculum includes lectures, exercises, case studies, and practical sessions, preparing students for real-world population studies and development planning.
- Course context, prerequisites.
- General objectives.
What is the structured plan for the Demographic Surveys course?
The course is structured into five distinct 3-hour sessions, progressively covering survey methodologies. This plan moves from foundational concepts to advanced sampling techniques, questionnaire design, data collection, quality control, and finally, demographic analysis and reporting. This systematic approach ensures students gain comprehensive expertise across all survey phases, preparing them for effective application in population studies and development planning.
- Session 1: Foundations.
- Session 2: Sampling.
- Session 3: Questionnaire.
- Session 4: Collection.
- Session 5: Analysis.
What are the fundamental concepts and historical context of demographic surveys?
Session 1 defines demographic surveys, distinguishing them from censuses, and introduces key concepts like population, sample, and sampling frame. It traces historical evolution from pioneers to global initiatives like DHS/EMMUS, highlighting Haiti's participation. Typologies by coverage, temporality, and theme are covered, outlining the eight-phase survey cycle and differentiating sampling from non-sampling errors.
- Definitions, history.
- Typologies.
- Survey cycle.
- Error sources.
How are sampling theory and various sampling plans applied in demographic surveys?
Session 2 explores core sampling theory, distinguishing probabilistic from non-probabilistic methods. It details Simple Random Sampling (SAS), Stratified Sampling for improved representation, and Cluster Sampling for efficiency. Systematic Sampling for household listings is also covered. The session concludes with the EDS/EMMUS stratified two-stage plan and crucial sample size calculation, ensuring statistical validity.
- Probabilistic sampling.
- SAS, stratified, cluster, systematic.
- EDS/EMMUS plan.
- Sample size calculation.
How do we design effective questionnaires and data collection tools for demographic surveys?
Session 3 focuses on designing effective questionnaires, emphasizing clarity, cultural adaptation, and standardization. It examines various question types—closed, open, filter, and skip logic—and outlines fundamental formulation rules, addressing cultural sensitivity. Pre-testing and CAPI advantages for real-time quality control are discussed, alongside the essential interviewer's manual.
- Questionnaire design.
- Question types.
- Thematic modules.
- Formulation rules.
- Pre-test.
- CAPI.
- Interviewer manual.
What are the best practices for data collection, quality control, and processing in surveys?
Session 4 covers practical data collection, emphasizing robust quality control and efficient data processing. It outlines field team organization and the informed consent protocol, crucial for ethical data gathering. Multi-level quality control, from initial checks to re-interviews and CAPI monitoring, is stressed for fraud detection. Data cleaning, including outlier detection and handling missing values, and data weighting are also covered.
- Field organization.
- Informed consent.
- Quality control.
- Data cleaning.
- Weighting.
- Tabulation.
How are demographic data analyzed and presented in a comprehensive report?
Session 5 transforms raw survey data into meaningful demographic indicators, such as fertility (TFR) and mortality rates. It covers variance estimation and statistical tests using software like R. The session details the standard structure of a survey report, emphasizing clear presentation of tables and graphs. Strategies for communicating results to policymakers, highlighting trends and policy implications, are also discussed.
- Demographic analysis.
- Fertility, mortality indicators.
- Variance estimation.
- Report writing.
- Determinant analysis.
How will student performance be evaluated in this course?
Student performance in the Demographic Surveys course will be assessed through a balanced evaluation system comprising continuous assessment (40%) and a final examination (60%). Continuous assessment includes active participation, practical assignments across the five sessions, and a group presentation. The final examination is comprehensive, featuring course questions, a practical sampling problem, and a critical analysis of an existing survey.

Frequently Asked Questions
What is the primary objective of the Demographic Surveys course?
It equips students to design, implement, analyze, and report demographic surveys, particularly in resource-limited settings, ensuring valid inferences.
What is the difference between sampling and non-sampling errors?
Sampling errors are random and calculable; non-sampling errors are systematic biases not reduced by sample size.
Why is pre-testing a questionnaire important?
Pre-testing ensures clarity, correct duration, accurate translation, proper skip patterns, and CAPI system functionality.
How does Computer-Assisted Personal Interviewing (CAPI) improve data quality?
CAPI provides real-time consistency checks, automatic skips, GPS tracking, and central monitoring, reducing errors and enhancing efficiency.
What is the purpose of data weighting in demographic surveys?
Weighting corrects for unequal inclusion probabilities and non-response, ensuring survey results accurately represent the target population.
