In this paper, our objective was to investigate whether the Covid-19 pandemic disease is more likely to break out in some specific age group or not. We also intended to know whether some specific demographic parameters like birth rate, death rate controls the spreading of the disease. Our investigation showed that the post reproductive population group is more prone to the disease for the countries having population pyramid of stationary or contracting type where as for the countries with expanding population pyramid, the pre reproductive population is more likely to be attacked by the disease. We also found the domains of values of the demographic parameters that result different dynamic phenomena. Further we tried to know whether a countrys population pyramid has an effect in spreading the disease. Our experiment showed that for countries having expanding population pyramid, the total number of cases is expected to be comparatively low whereas for countries having contracting population pyramid, the total number of cases is expected to be comparatively high.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
