There is a particular need for the inclusion of a question on the continuity of services in terms of access to mains water, electricity and natural gas, so as to reflect any deprivations that would not be revealed by merely asking whether households are connected to these networks. The collection of information on multiple dimensions in the same survey would also enable analysis of the interplay of different dimensions, their combined distribution and causal interrelationships, which would facilitate the formulation and monitoring of policies. It is to be hoped that the various efforts being made in the region, under the banner of the Statistical Conference of the Americas of ECLAC, or globally through initiatives such as the International Household Survey Network, will give rise to the greater availability of more useful and reliable sources of information that can adequately meet the growing demand for information.
