The municipality inventory can also be used to learn more about how the number of municipalities evolved over time in Switzerland.

1) To get the number of municipalities over time:

# Import the municipality inventory
mutations_object <- import_CH_municipality_inventory(file_path = path_inventory_xml)

# Specify a date vector
dates <- seq.Date(from = as.Date("1980-01-01"), to = as.Date("2020-01-01"), by = "1 year")

# Obtain the municipality count for this date vector
sy_municipality <- municipality_counter(mutations_object$mutations, dates, geo_level = "ch")

# Second example for one point in time:
sy_municipality <- municipality_counter(mutations_object$mutations, "2001-04-04", geo_level = "ch")

2) To get the number of municipalities over time per canton:

mutations_object <- import_CH_municipality_inventory(file_path = path_inventory_xml)

dates <- seq.Date(from = as.Date("1980-01-01"), to = as.Date("2020-01-01"), by = "1 year")
sy_municipality <- municipality_counter(mutations_object$mutations, dates, geo_level = "cantons")
