The trend of mortality is liable to change during a pandemic and there was increase in number of deaths due to COVID-19. This study is done to determine the mortality trends noted in Tamil Nadu from 2019-2022.
OBJECTIVES : The objectives is to determine the trend in all-cause mortality among total population from 2019-2022 and to determine whether there is any difference in mortality among different age groups, genders and among districts for the years 2019-2022
METHODOLOGY : It was descriptive study from the Civil Registration System data of Tamil Nadu from 2019-2022. Data were collected in excel sheet and calculated mortality rates for total population, both genders, different age groups and by districts for the year 2019-2022.
RESULTS : We analysed all mortality records from 2019-2022. A peak in the all-cause mortality (11.44/1000 population) was noted during the COVID-19 Pandemic (2021) which started to decline Post COVID-19 in 2022 (9.07/1000 population), although the mortality was slightly higher compared to Pre COVID-19 period (2019). Similar pattern was observed in both gender. Male mortality was higher than Female mortality in all four years. Among Age groups, there was a drastic increase of mortality in 60 plus age group during COVID-19 (57/1000 population).

Gender specific mortality trend is higher in male compared to Female population in Tamil Nadu. Age specific mortality is higher in 60+ age group and it peaked up during 2021 which might be due to the effect of Pandemic.
