Around everywhere I've lived (in the US), "pole pig" transformers 
usually supply more than one house as well, especially in urban areas.  
About the only places they don't are for heavy industrial/commercial 
buildings, or in rural areas where there's 1/4mi or more between you 
and your closest neighbor...

And, I guess, multi-unit apartment buildings tend to have their own 
transformer as well.
