   WHO declaration triggers synchronized global lockdowns, an oil-demand collapse (WTI briefly trades negative on 20 April 2020), and unprecedented fiscal/monetary stimulus across every country in this database.

   چرایی این پیوند: The crude death rate, on a smooth decades-long secular decline and sitting at a series-low 4.66 per 1,000 in 2019, jumped to 6.44 (2020) and 6.39 (2021) -- a roughly 37% spike -- before reverting to 4.90 (2022) and 4.75 (2023): a textbook excess-mortality signature of the pandemic imposed on an otherwise flat, mature mortality trend.

   ملاحظه: None substantial -- the sharp, temporary, fully-reverting nature of this spike against a very smooth prior trend makes this one of the cleanest single-event signatures in the whole database.
