Why is it that there are more stars at night in the rural areas than in ubarn areas?

Now I am certainly no scientific expert, but I believe
that the answer lies in the term light pollution. I have pasted a link below to a page
on light pollution which should hopefully give you more information about this
phenomenon, however, the basic idea is that there are the same amount of stars in the
night sky in both urban and rural landscapes. The crucial difference is that in urban
landscapes there is a high level of light pollution or lots of streetlights and lights
from other buildings that result in a kind of glow that prevents us from seeing many
stars, if any at all. In rural locations, there are less people and therefore less
lights, resulting in a much lower level of light pollution and giving us an open night
sky, free to be viewed in all of its glory. I remember once going to the centre of
London one evening and being surprised at the kind of glow that there was in the sky.
Needless to say, I couldn't see any stars at all.
