6. Baumol's cost disease
1966 publication from William Baumol and William Bowen : Performing Arts, The Economic Dilemma
Some economic activities, called "archaic", are not likely to achieve productivity gains over the long term.
The time and effort of census enumerators needed to collect information from 1000 people has hardly diminished during the past 100 years.
But enumerators salaries increase in the long run, with the average salaries in the country

7. Cost of the census collect in countries making complete surveys

8. Beaumol effect and traditional census
The more an economy is developped, the more the costs of a complete enumeration appears high.
Either governments accept to pay more and more, either traditional census will disappear.
Alternative census methods are not concernerd by the Beaumol effect

9. Conclusion
Most of the rich countries using traditional census are considering an evolution of their census statistical model
Among less wealthy countries, half are also considering such a move.
It is likely that during the next census rounds alternative methods will expend in parallel with the rising standard of living in all regions of the UNECE.
