In your country, which towns and cities have an ethnic composition roughly average for the country?

Very interesting thanks. In Colombia's case, it would be really hard to pinpoint somewhere with a close-to-average ethnic composition, as the country is really split into a minimum of two very distinct regions - Andes vs coast. Plus also the rural border regions with the other countries have relatively substantial Amerindian communities.

Es una pregunta interesante para el caso de Colombia, y siendo un país tan heterogeneo, it's hard to say.

I have read about Barranquilla and Santa Marta albeit being coastal cities, have both many triracials and many mestizo to white people. Maybe some Colombian department half way between the coast and the Andes could have an ethnic composition in-between?

Barranquilla is the most diverse city in Colombia, but it's also too Caribbean to represent the country as a whole.

I think departments like Cesar and Cordoba, located in both Caribbean and Andean region, could be near to be representative. They have mostly mestizo/pardo population, with black, native and white minorities (including settlers from Santanderes and Paisa region). However, they have less Euro admixture and more SSA admixture than the national average.

Another candidate could be Valle del Cauca department. It has a similar genetic admixture compared with they national average, but its black population is segregated, with few pardos/mulattos.

For Ecuador, I think most representative province is Santo Domingo. It was part of Pichincha province until 2007, so there are a lot of Andean settlers, while the local culture is mostly Coastal. They also have indigenous population (tsachilas) and blacks from near Esmeralda province, as well as a lot of Colombian immigrants.

In what way? Internal diversity from across Colombia and its own racial spectrum, or in terms of recent(ish) immigrants and their descendants?

Since it's the average, I guess many towns and cities will. The biggest with that characteristic should be Varna I guess (85% Bulgarians).

Both. Colombia had not many post colonial immigration so, unlike Barranquilla, White population is from colonial stock. In the other hand, most population in Barranquilla is in pardo spectrum, with few blacks and almost any native population. It contrasts with the rest of Colombia, where SSA admixture is more segregated, and we can find some native population relatively pure.
