Language stack
The roles this state's languages play, with a share where a census gives one.
How this is measured

Labels from the States sheet; no census share yet.
Official-language count: 1. Diversity below is country-level.
Languages of Czech Republic
Country-level shares: CLDR, with a census or survey where CLDR has none. They overlap and are never normalised.
How this is measured
Effective number of languages 1.00, Greenberg diversity 0.00, both on the raw shares and country-level.
How far lingua francas reach
Share able to hold a conversation, first or second language.
How this is measured
Each row carries its source tier. A Tier 1 census figure is this state's own; a Tier 3 figure is the country's, not this state's.
