Drivers of Population Change

The Office for National Statistics produce data estimating the components of population change.  These figures for Sandwell indicate that Sandwell's population growth is being driven by natural change (births minus deaths) and International net migration. While Sandwell loses population through internal net migration.  Internal migration is defined as residential moves between different Local Authorities in the UK.

However, the volume of population turnover produced though international migration in Sandwell is far smaller than that generated through internal migration.  Figures for the change between 2017 and 2018 highlight this:

Internal migration; Inflow 15,409, Outflow 16,897, Net  -1,488

International migration; Inflow 2,787, Outflow 887, Net 1,900

Population Estimates - Explained

The population of the UK is only counted once every ten years at the time of the Census, the latest Census being in 2011. In the years between, the Office for National Statistics produce 'estimates' of the population at a variety of geographical levels and by age and gender. The latest estimates are for mid-year 2018. They are the building blocks for a wide range of National Statistics. They are used directly as a base for other secondary population statistics, such as population projections and population estimates for small geographical areas. They are used for weighting survey estimates such as the Labour Force Survey and other social surveys to ensure that they are representative of the total population, and they are used as denominators for rates or ratios, for example in health and economic indicators. Population estimates are produced from administrative records on births and deaths and from estimates of Long-Term International Migration (LTIM) in addition to other adjustments and use the most recent Census as their base. Data on births and deaths is considered very reliable but migration data is not and this is where much of the uncertainty lies in producing estimates. The 2018 Mid-Year Population Estimates were released on the 26th June 2019.
