SMMT: Municipality statistics

19.05.2024

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")
