How international is Switzerland –– back then and now? This Swiss un-roll compares counts of Mother tongues (Swiss vs non-Swiss) for each canton (or Bezirk and Gemeinde) in each of four years (1970, 1980, 1990 and 2000) in Basel Land. The data were downloaded from http://bfs.admin.ch/ theme 40.1 using the STAT-TAB pages.
