ive done about this in geography, italy population is starting to decrease or son to be (they say italy in stage 5 of the demographic transition model) so italy population will be decreasing.
so are many other countries soon to be if things don't change. e.g. britain, australia (they said to be in stage 4 of the DTM, close to stage 5) and germany is said to be in stage 5 also or near to it. not just italy's problem but many other countries too.
