Research Insights: Why Has COVID-19 Affected Some Cities More than Others?
Authors:   Inter-American Development Bank
Published: February 2022

Algunas de las variables relacionadas con el impacto de la COVID-19 a nivel de las ciudades son similares en contextos muy diferentes. Tanto en Brasil como en Estados Unidos, por ejemplo, la densidad demográfica se asocia con un número más alto de muertes per cápita por COVID-19. Otras variables relacionadas con el impacto local de la pandemia se comportan de manera diferente dependiendo del contexto. En Brasil, en las ciudades con un ingreso medio más alto hubo relativamente menos personas que decidieron quedarse en casa y más muertes por COVID-19; en Estados Unidos sucedió lo contrario. Las ciudades con niveles más altos de vulnerabilidad socioeconómica en Brasil experimentaron más muertes per cápita a pesar de la mayor tendencia de su población a quedarse en casa en los primeros meses de la pandemia.
