An understanding of the size and structure of Dudley Borough's population is key to planning current and future services, measuring the health of local people and identifying health inequalities.  Estimates of the resident mid-year population by age and sex are produced every year by the Office for National Statistics (ONS).  They are published at the end of June a year in arrears, so the 2018 mid-year estimates were published in June 2019.  The two main contributors to population change are natural change, which is the number of births minus deaths, and net migration, which is the difference between long-terms moves into and out of the United Kingdom or local areas.
