Venezuelan COVID figures [and Nature infographics of the week]

Nature has started a  “week in infographics” column with a rather poor panel of figures the first time I checked (single numbers represented by surfaces and so on), but this week shows an unquestionable rendering of the discrepancy between the official COVID-19 death rates in Venezuela and in neighbouring countries. Obviously, there is no reason for all countries to share the same patterns (as seen for instance with the huge difference between France and Germany during the first wave in 2020), especially when considering the economic state of Venezuela, with very few entries from abroad and a general lack of movement throughout the country, but the attached Nature article argues that there is indeed a severe undercounting/reporting. The statistics that exist are actually gathered by a clandestine network of epidemiologists and doctors, with an impossibility to cross-check these as the baseline excess death statistics are not available either. Since 2016. The network responsible for the data collection is clandestine as the scientists involved risk detention or being fired from their position, despite the terrible lack of doctors and medical facilities in the country (which I observed in 2007 when getting an anti-rabies shot proved impossible!)… Another “shoot the messenger” in another dictatorship…

subway commute distribution [nice graphics]

An infographics entry in the New York Times about the distribution of a commute between two arbitrary subway stations in New York City, including a comparison of the distribution of a similar (?) commute by Tube in London. Showing that in most cases, the tail is thinner in London than in New York City. (Warning: the comparison may switch scales.)

Here is a bit of an outlier:

given that the two distributions hardly overlap and still share a similar median commute time!

la peste gagne…
