Yes, really. If it makes you feel better, here is the source information provided at the bottom of the article if you had bothered to read it. Or did the NYT make this up?
About the data: The all-cause mortality data obtained from each country varies: Some countries publish daily death totals dating back decades, and others only for the last few years. Places with less historical data, such as Istanbul, make for rougher historical comparisons. Historical baselines used to calculate excess deaths do not adjust for changes in population or any expected reduction in recent deaths from non-Covid-19 causes. And they do not adjust for two deadly flu epidemics in Europe during the winters of 2014-15 and 2017-18. The count of recent deaths in New York City includes city residents only, while data from previous years includes all deaths in the city regardless of residence.
