**SOURCE:** **Source for population of Scotland:** Mid-year population estimates published by National Records of Scotland (NRS). The estimated population includes all those usually resident, whatever their nationality. Members of UK and non-UK armed forces stationed in Scotland are included; UK forces stationed outside Scotland are excluded. Short-term international migrants are excluded. Scottish mid-year population estimates are National Statistics. Data is published on this website (http://www.nrscotland.gov.uk/) and are summarised in the High Level Summary: http://www.nrscotland.gov.uk/statistics-and-data/statistics/stats-at-a-glance/high-level-summary-of-statistics-trends Estimates are usually published annually in April of the following year so mid-2016 estimates will be published in April 2017 and mid-2017 estimates should be published in April 2018. The estimates for mid-2002 onwards are based on the 2011 Census. The estimates for mid-2002 to mid-2010 were revised on 17 December 2013 to take into account the results from the 2011 Census. Previously the estimates for mid-2002 to mid-2010 were based on the 2001 Census. More information on the differences between the old and revised estimates can be found on the NRS website (http://www.nrscotland.gov.uk/statistics-and-data/statistics/statistics-by-theme/population/population-estimates/mid-year-population-estimates). The estimates for mid-2012, mid-2013 and mid-2014 were revised on 28 April 2016 to correct errors affecting the age distribution of the population, the total population of Scotland for these years did not change. Scottish population estimates are produced using the demographic cohort component method. The estimates are based on the most recent census. Each year the population is 'aged on' one year (that is, the 0 year olds become 1 year olds and so on), the number of births in the year are added, the number of deaths subtracted and adjustments made for estimated migration (based on the best proxy sources available) and other changes in special populations. **Source for population of EU15:** Start of year population estimates are published by Eurostat. Population growth for the EU15 will be measured using the total (combined) population of the 15 countries - this is a **weighted** approach. An alternative approach is to use an unweighted measure, where each of the 15 countries individual population growth rates are added together and the total divided by 15 to give an EU15 countries' average. Data is published on the Eurostat website, and can be found at, http://ec.europa.eu/eurostat Eurostat provides two population figures for France. For measuring progress against the target we use the 'France Metropolitaine' figure, which covers the French population residing in Europe. EuroStat also revise their population estimates when new estimates are provided to them. **Source for Healthy Life Expectancy:** Produced by ISD / ScotPHO using National Records Scotland population estimates and death registrations and General Household Survey/Scottish Household Survey data on self-assessed health. HLE is derived by combining estimates of life expectancy (LE) in years with data on self-assessed health (from surveys). The three individual elements which feed into this measure are National Statistics but the measure itself isn't. These data are owned by the Scottish Public Health Observatory (ScotPHO), within the Information and Statistics Division (ISD). Data are updated annually on the ScotPHO website at: http://www.scotpho.org.uk/population-dynamics/healthy-life-expectancy/introduction HLE is derived by combining estimates of life expectancy (LE) with data on self-assessed health (from surveys). Estimates of HLE are less robust than estimates of LE due to the use of survey data; the fact that health status is self-assessed brings in an element of potential bias to the estimates. HLE estimates have much wider confidence intervals than LE estimates. The methodology changed in 2009 due to a change in the question used to measure self-assessed health. This change brings Scottish HLE estimates into line with the UK and other EU countries.
