Furthermore, disaggregated data coverage is variable by population groups, with data on some groups such as IDPs being particularly poor. Demographic Characteristics Despite UNHCR’s efforts to improve data availability, it has continued to be difficult to obtain disaggregated data in many countries where the agency is not involved in primary data collection, with a substantial number of countries not reporting disaggregated data to UNHCR. The number of countries reporting at least some sex-disaggregated data has remained steady in 2017 at 147 countries. Similarly, the population covered by sex-disaggregated data has decreased slightly from 2016, now at 59 per cent as opposed to 60 per cent in the previous year [Figure 18]. According to the available data, overall men and women were almost equally represented in the population of concern, with 21.3 million men and 21.0 million women.74 Coverage of the population of concern by age was lower than for sex. In 2017, 136 countries reported at least some age-disaggregated data but which 58 ‘09 ‘10 ‘11 ‘12 ‘13 ‘14 ‘15 ‘16 ‘17 Age-disaggregated data available covered only 38 per cent of the entire population of concern, an increase on the 25 per cent of the previous year but when a higher number of countries (141) reported data. Out of the 27.0 million people for which age-disaggregated data is available, 14.2 million or 53 per cent were children under the age of 18. Refugees and asylum-seekers tended to have the best coverage. In 2017, sex-disaggregated data were available for 12.6 million refugees and agedisaggregated data for 11.9 million (out of the 19.9 million total population). This represents 63 per cent and 60 per cent of the total refugee population, respectively, a small improvement on the previous year when the equivalent coverage was 62 per cent and 56 per cent. Among IDPs, sex disaggregation covered 61 per cent of the population compared with 32 per cent for age-disaggregated data coverage. For asylum-seekers, the coverage was 55 per cent for sex-disaggregated data and 45 per cent for disaggregation by age. For the other types of population of concern reported to UNHCR, the figures for sex and age disaggregation were as follows: returned IDPs (24 per cent and 16 per cent, respectively), others of concern (69 per cent and 45 per 74 UNHCR’s population of concern includes refugees, IDPs, returnees, others of concern, and stateless people. unhcr > Global trends 2017
