Remember 2012, the supposed year of Doomsday?

Authors: Rashmini Rathnaweera, Rashmi Jayasekara, Chalani Pradeepika

 

2012 marked the end of one of the cycles of the ancient Mayan Calendar but, with a scientific perspective, 2012 was the year that the newly discovered planet Nibiru was supposedly headed towards Earth, entailing a catastrophic collision. Despite all the speculations, 2012 ended up being a typical year but the data suggests otherwise. When looking at the past statistics of the annual population growth of Sri Lanka from 1960 – 2018, there is a sudden atypical drop in 2012. As intriguing as it may seem, when further investigated as to what this actually implied, it was found that such phenomena are more commonly known as population shocks; a sudden reduction in a human population size caused by many factors.

Sri Lanka has been battling the COVID-19 pandemic since 2020 and the country is yet to recover from it. So, it led to the exploration, what sort of a population shock will be caused by COVID-19? This was quantified through an Excess mortality measure known as P-score. There are two components to the P-score value; total deaths that would have occurred without COVID-19 and total deaths due to COVID-19, assuming all other conditions remain the same. The former component was calculated through a time series ARIMA model fitted to total annual deaths in Sri Lanka from 1948-2003 and the model was validated through total annual deaths in Sri Lanka from 2004 to 2018. The latter component was obtained with the aid of the COVID-19 deaths predicted and published by the Institute of Health Metric and Evaluation (IHME).

Accordingly, the forecasted excess mortality for Sri Lanka for the year 2020 and 2021 comparative to the last 5 years is 9% and 17%. There is almost double the increase in mortality in just one year.
