I???m using Zonal Statistics as a Table in ArcGIS 10 to get Min, Max and Mean values.

My Input or feature zone data is a country shapefile with a certain number of provinces
The input value raster is an image with the same extent (country shape)

What I need is to have values in all provinces, but I???m getting an output table with less number of provinces (for example the number decreased to 90, from 140)
I can???t figure out what could be the problem, why it doesn???t consider the other provinces.
