3. Benefits of census using registers*
Cost savings expected by almost all countries
using registers
Expected cost savings very high (85% to 99%)
when there is no field data collection
Significant cost savings (40% - 75%) with adhoc sample surveys
Lower or no cost savings with full enumeration
Data on actual cost savings still limited
Costs for setting up and maintaining registers

3. Benefits of census using registers*
Time savings expected by about half of the
countries using registers
Difficult to estimate time savings in advance
Turkey estimates 50% compared to trad. census
Israel reported actual time savings (not quantified)
Most countries with register-based census did not
report expecting time savings
Germany and Poland reported potential risk for
increasing time to produce results

5. Conclusions: Trends on census
methodology in UNECE region
Trend to move away from traditional census,
particularly in European Union
Number of countries using registers more
than doubled from 2000 to 2010 round
Diversification of methodology: combined
census approaches increasingly popular
In CIS and SEE, traditional census still the
favorite method, but increasing interest in using
registers
