Increases in international funding for health have been accompanied by accelerating demand for more and better statistics, which are needed to track performance and ensure accountability. Worldwide interest in the monitoring of development, as exemplified in the Millennium Development Goals (MDGs), generates pressure for high-quality and timely data for reporting on country progress. This rapid escalation of demand has exposed major gaps in the supply of health statistics for developing countries but also provides major opportunities to increase the supply and use of sound health statistics. First, the emphasis on monitoring and evaluation is leading to proliferation of indicators and excessive reporting requirements, and needs to be refocused on systematic investments in data generation and analysis. Second, the risk of inadequate or poorly targeted investments can be kept to a minimum by understanding the causes of poor availability of health statistics, including lack of accurate measurement instruments, application of suboptimum methods of data collection, and inadequate use of methods and analyses to produce comparable estimates. Third, the preoccupation with MDGs does not take into account the rapid health transition, which implies that health statistics should systematically include a much wider array of health issues from acute infectious diseases to chronic non-communicable diseases and injuries, disaggregated by socioeconomic position. Fourth, the growing number of national household surveys, which are the main source of most population health statistics, need to be streamlined into cohesive and comprehensive country health survey programmes. Now is the time to accelerate the production and use of accurate, complete, and timely health statistics for decision-making by investing in country health information systems that should be based on an efficient and effective mix of standardised methods of data collection and analysis that meet country and international needs.
