relatively homogenous

Some may be surprised by the cultural diversity this rather small country packs:

It has four main linguistic and cultural regions: German, French, Italian and Romansh. Although most Swiss are German-speaking, national identity is fairly cohesive, being rooted in a common historical background, shared values such as federalism and direct democracy,[15][page needed] and Alpine symbolism.[16][17] Swiss identity transcends language, ethnicity, and religion, leading to Switzerland being described as a Willensnation ("nation of volition") rather than a nation state.[18]

Due to its linguistic diversity, Switzerland is known by multiple native names: Schweiz [ˈʃvaɪts] (German);[f][g] Suisse [sɥis(ə)] (French); Svizzera [ˈzvittsera] (Italian); and Svizra [ˈʒviːtsrɐ, ˈʒviːtsʁɐ] (Romansh).[h] On coins and stamps, the Latin name, Confoederatio Helvetica — frequently shortened to "Helvetia" — is used instead of the spoken languages.

I also think the local traditions differentiating down to single villages are more important and alive than in other countries.

But yes, "national identity is fairly cohesive", maybe you meant that.
