EGM ON INNOVATIONS TO STRUCTURED DATA COLLECTION METHOD New York, 4-6 Dec 2019 Cartographic Assessment and Quality Assurance for the Haiti’s 5 th Population and Housing Census By : Daniel Milbin, National Director of the Census project, IHSI Mohamed Laghdaf Cheikh Melainine, Chief Technical Adviser – Census, UNFPA
OUTLINE ≈ 18 min • Introduction • Census methodology • Use of Cartography in Data Quality assessment • Lessons learnt • Conclusion
CONTEXT Haiti’s 5 th Census is the first digital census to be conducted in the country, a gender sensitive census, and one of the first censuses of the 2020 census round in the Latin America and Caribbean region. Haiti’s Census intervenes in a context of rarity of reliable statistical data in the country, where population censuses remain the most reliable data source. The last census in the country was conducted 16 years ago, while the UN recommends conducting a population census every ten years.
METHODOLOGY Pilot Census • De Juré Census • • Enumeration conducted in June-August Each Enumerator is assigned 1 EA 2018. • Direct Interview with the HHH • 120 EA, 4 Departments, 8 communes • 2 months field staff training • 232 Field staff. • 8 weeks Data Collection • Data collection monitored almost in real • PES is planned time. • • Wide dissemination and use of Transparent and exhaustive evaluation - Census results. 220 recommendations
