Habitat Debate. 2001 Jun; 7(2): p..Population and household projections are of crucial importance to both policy makers and researchers who depend on timely and reliable projections to make informed decisions and to produce quality research studies. Currently, one of the most problematic areas regarding projections is the demographic impact of the HIV/AIDS epidemic in countries with high prevalence rates i.e. how the epidemic is influencing population and household projections. At the end of the year 2000, 36.1 million people were estimated to be living with HIV/AIDS, of which 1.4 million were children. 47 per cent of the infected adults were women. 5.3 million people will be newly infected during this year. The pandemic does not spread homogeneously. The number of infections, the risk of dying, the access to medication and the principal transmission ways vary worldwide, and so does the impact of the HIV/AIDS epidemic on population structure and on household formation. In countries where the epidemic is endemic in the general population, the impact on the age and gender structure of the population is significant, and changes in the social context and behaviour are certain.

The potential of national household survey programmes for monitoring and evaluating primary health care in developing countries. L'apport potentiel des enquetes nationales sur les menages a la surveillance et a l'evaluation des soins de sante primaires dans les pays en developpement.
World Health Statistics Quarterly. Rapport Trimestriel de Statistiques Sanitaires Mondiales. 1985; 38(1):38-64.National programs of household sample surveys, such as those being encouraged through the National Household Survey Capability Program (NHSCP), are a principal source of information on primary health care in developing countries. Being representative of the total population, the major population subgroups and geographic subdivisions, they permit calculation of health status and utilization of health services. Household surveys have an important role to play in monitoring and evaluating primary health care since they sample directly the intended beneficiaries, and so can be used to judge the extent to which programs are meeting expected goals. Caution is necessary, however, since methodological problems have been experienced for many evaluation surveys. National surveys are especially appropriate for measuring many indicators of progress towards national goals within a broad socioeconomic perspective. Future directions in making the optimum use of household surveys for health program purposes are indicated. The NHSCP is a major undertaking of the UN system including WHO to collaborate with developing countries to establish a continuing flow of integrated statistics on a recurrent basis to support the national development process and information priorities. It brings together the principal users and producers of data to plan and conduct surveys which respond to national needs and priorities. The NHSCP encourages countries to employ a permanent national field organization for data collection. Areas of discussion are: the potential for monitoring and evaluation, the household survey as a source of health indicators, the demand for household surveys of health, followed by a summary of the health and health-related topics covered by 6 national health and nutrition surveys conducted in several developing countries. The special themes of infant and child mortality, morbidity and nutritional surveillance are also considered. The experience of many developed countries has been very positive with the use of nonmedically organized health surveys. Although the sample survey can be used in many settings to obtain population-based data, it must be carefully designed and implemented according to scientific procedures in order for the results to be validly extrapolated to the population or subgroups of primary concern.
