Data provide you with useful information that can be processed into a more readily accessible form for use by policy-makers and the public. Data can be linked to important societal issues when placed in the context of a relevant issue. For example:
- data on the number of patients with respiratory disease can provide information on the impact of air pollution;
- the number of cars in urban centres can help provide estimates on the magnitude of air quality problems;
- data on the quantity or quality of natural habitat can help assess, among others, the availability of species for traditional resource users such as trappers or hunters; and
- the composition of solid waste can clearly indicate some emerging issues, such as the problems associated with electronic waste in China and India.
