Please provide the number of deaths where nitrous oxide or nitrogen is mentioned on the death certificate from January 2012 - August 2022.

Thank you for your request.

We hold the following analysis, which looks specifically at deaths involving volatile substances from 2001 to 2020: Deaths related to volatile substances, helium and nitrogen in England and Wales. These statistics are based on the year of death registration. Because of death registration delays, around half of these deaths will have occurred in previous years to which they were registered in, and the majority will have occurred before the coronavirus (COVID-19) pandemic.

We have also published the following user requested data sets:

Due to registration delays, we do not yet hold data for 2022. Statistics on mortality are derived from the information provided when deaths are certified and registered. Quality and methodology information is available in the Mortality statistics in England and Wales Quality and Methodology Information (QMI), and the User guide to mortality statistics.

If this does not meet your needs, we can provide a bespoke data set containing data 2012-2021. Special extracts and tabulations of mortality data are available to order from the Health and Life Events (HALE) Customer Services team. These extracts are subject to disclosure control, legal frameworks, resource, and agreement to costs under the ONS Charging policy.
