Deaths by local authority of usual residence, numbers and standardised mortality ratios (SMRs) by sex.SMR measures whether the population of an area has a higher or lower number of deaths than expected based on the age profile of the population (more deaths are expected in older populations). The SMR is defined as follows: SMR = (Observed no. of deaths per year)/(Expected no. of deaths per year).SMRs are calculated using the previous year's mid-year population estimates. Live birth figures are used for calculations involving deaths under 1 year.The age-standardised mortality rates in this release are directly age-standardised to the European Standard Population, which cover all ages and allows comparisons between populations with different age structures, including between males and females and over time.Note: SMR and deaths by sex data only available since 2001.Download from ONS website
