As explained earlier in this chapter, mainstreaming a gender perspective in statistics means ensuring that gender issues and gender-based biases are systematically taken into account, in the production of all official statistics and at all stages of data production. This strategic process ensures (a) that national statistical systems regularly collect, analyse and disseminate data that address relevant gender issues, (b) that gender-sensitive concepts and methods are used in data collection in all statistical fields, and (c) that the presentation and dissemination of gender statistics aim to reach a wide range of users, including policymakers, advocates, researchers and analysts whose primary concerns are not necessarily focused on gender. In the more developed regions, gender is already mainstreamed in the production of many national statistical systems and the quality of gender statistics is ensured by way of overall quality frameworks for statistics. However, in the less developed regions, many countries are still struggling to produce, on a regular basis, quality data that can be used to tackle relevant gender issues.
