Longitudinal two-mode European Values Study, 1990 and 2008 (EVS 2020)

Source: R/data_mpn.R

mpn_evs_ita, mpn_evs_deu, and mpn_evs_gbr each hold one country's European Values Study data for 1990 and 2008 in a single two-mode network. Respondents form the first mode and the 14 types of association form the second. The time tie attribute records the year, either 1990 or 2008.

Italy has 1198 respondents, Germany 1872, and the United Kingdom 1402.

Details

These are repeated cross-sections, not a panel. The European Values Study draws a new sample each round, so no respondent appears in both years.

Use over_time() rather than over_waves() on these objects. over_time() restricts each year to the respondents sampled in it. over_waves() keeps the whole node set in each wave, which understates the density of each year.

over_time(mpn_evs_ita, netrics::net_by_density, attribute = "time")
