This dataset provides mortality statistics for England and Wales, broken down by calendar year of registration, age, sex, underlying cause of death and area of usual residence of the deceased.
         
         Important information for interpreting these mortality statistics:
         
         
* death statistics are compiled from information supplied when deaths are certified and registered as part of civil registration, a legal requirement
* figures represent the number of deaths registered in the calendar year
* figures represent deaths which occurred in England and Wales - these include the deaths of individuals whose usual residence was outside England and Wales
         Deaths should be registered within 5 days of the date of death although there are some situations when the registration of a death will be delayed, such as those reported to a coroner. Information on https://www.ons.gov.uk/peoplepopulationandcommunity/birthsdeathsandmarriages/deaths/methodologies/impactofregistrationdelaysonmortalitystatistics2016[the impact of registration delays for a range of causes] is available.
         
         To protect the confidentiality of individuals, small counts output for areas below region level are rounded; counts of 0, 1, and 2 are rounded to 0, while counts of 3, 4, and 5 are rounded to 5.
