text: sources of data ... but in general the topics covered should be determined upon a balanced consideration of : (a) The needs of the country, national as well as local, to be served by the census data; (b) The achievement of the maximum degree of international comparability, both within regions and on a world-wide basis; (c) The probable willingness and ability of respondents to give adequate information on the topics; (d) The technical competence of the enxomerators to obtain information on the topics by direct obseirvation; and (e) The total national resources available for enumeration, processing tabulation and publication, which will determine the overall feasible scope of the census. 11/ 22. It should be noted that point (c) above will need addressing, particularly in the context of human rights. Movements have emerged in several countries arguing that the information collected in national censuses contravenes the right to privacy. Should the provision of personal information be considered a social responsibility or does - or can - this information threaten an individual's privacy? 23. In extremely general terms, reliable data is available for many of the more basic indicators, such as those relating to demography, GNP per capita, infant mortality, life expectancy at birth, child literacy rates, primary school enrolment and others. 12/ Yet for some indicators which are closely linked to the realization of economic, social and cultural rights, data availability remains a dilemma. According to the United Nations Children's Fund (UNICEF) several areas where indicator coverage has yet to become comprehensive are: percentage share of household income disaggregated into the lowest 40 per cent and the highest 20 per cent; percentage of children under five suffering from mild, moderate or severe malnutrition; percentage of population below absolute poverty level, disaggregated into a rural and urban basis; adult literacy rates, mortality and fertility rates; percentage of central government expenditure allocated to health/education/defence and 
analysis: The text discusses the importance of considering various factors when determining the topics to be covered in a national census, including the needs of the country, international comparability, and the availability of resources. It also highlights the challenges of collecting reliable data on certain indicators, such as poverty rates and adult literacy, which are closely linked to the realization of economic, social, and cultural rights. This suggests that the category should be related to social and economic development, with a focus on human well-being and development indicators.
