I cannot remember off the top of my head, but did some study on this in 2006 globally for work.
Europe and the USA are opposites. Most automatics in Europe are high concentrations of certain models, such as big luxo cars like Jags, Mercedes-Benz Es & Ss, BMW 7s, London Taxis, etc. The number is single digits overall. Commerical vehicles are almost all manual.
Similar %, but opposite in the USA: primarily trucks, smaller cars with 4 cylinders, and sports cars. Most commerical large trucks are MTs (Eaton,etc.), but buses, garbage trucks, etc. are AT. Usually Allison.
Japan is binary: most all cars are automatic/CVT (heavy traffic) and almost all performance cars are MT. I saw a billboard for the Mazda 6 over there and you cannot get the regular 6 with a manual and you cannot get the Mazdaspeed 6 with an AT. Most all commerical vehciles are MT.
Korea is a mix. Mainly AT for cars, although there are many more MTs in regular cars than Japan. SUVs are a mix with MT more than AT - fuel economy and emissions regs, plus fuel cost. Commercial trucks are primarily MT.
Australia is mixed. There are a lot of automatics, but also a large percentage of manuals. NZ is different as they absorb a lot of used Japan market RHD cars for cheap (won't pass the tough Japan inspection) so there are a lot of automatics, but imported new cars are often manual.
The rest of the world is primarily manual, but certain models have ATs dominating, because they either are sold in high density traffic areas or are only available in that configuration in the home market.
Generally speaking, very high density areas and North America have more automatics, the rest have manuals for cost, fuel efficiency, and driving fun.
I'll have to see if can dig out the %s across markets. I have it somewhere.
Driving experience - no matter how small or cheap a car is seems to be must have to sell in Europe. Comfort/style is more important in NA, and techy things are big in Japan. That is a sweeping generalization, so there are segments that obviously the opposite in all these markets.
