The impact of the COVID-19 lockdown on collecting informal caregiving data within the LISS Panel in March 2020

In this research note, we assessed whether data on current informal caregiving collected in the LISS panel in March 2020 were structurally biased due to the COVID-19 Spring 2020 lockdown that was implemented during the time of fieldwork. By comparing answer patterns before and after March 15, the date where the first measurements against the spread of the COVID-19 virus were announced by the Dutch government, we conclude that the data collected before and during the Spring 2020 lockdown were not structurally different. Hence, we conclude that the data do not suffer from structural bias.
