They should be mapped as a polygon drawn around a group of contiguous building plots, on the line where they meet the street. They are equivalent to 'manzanas' in Spanish (e.g. Barcelona and Buenos Aires), 'îlots' in French, 'bouwblokken' in Dutch (e.g. Amsterdam), and 'kvarter' ('fastigheter' sharing the same name) in Swedish.
At a simple level they can be thought of as islands of private developable plots surrounded by public highway - as such, they should not include pavements or sidewalks. However, it should be noted that city blocks can contain public amenity space (e.g. parks and playgrounds) and so the distinction is primarily between land used for buildings or amenity space, and land used for streets/highways.
In some cities they are given identifying code numbers or names which, where no boundary polygon has been drawn, can be mapped by placing a node in the middle of the block.
Combination with Land Use
As noted on the landuse=residential page in the section 'Separation from roads', land use tags should generally not extend over the highway. Therefore city blocks can usefully be combined with land use tags where finer-grain plot-by-plot information is not available.
