How are WW1 or WW2 era bombs still regularly found in gardens and houses around UK and Europe?

Question

The day after or week after these were dropped 60-100 years ago, did people not think, there’s a bomb over there we should make it safe.

Edit: I singled out the UK because they discovered a bomb from World War Two today in Plymouth. I know the UK is still in Europe.

Answer 1

A lot of people evacuated – you don’t really stick around if there are bombs dropping every day.

There wasn’t enough skilled personal around to diffuse all the masses of explosives.

No one actually counted how many bombshell were dropped where and how many didn’t explode.
