In many countries today, people in cities either live alone or in small family units rather than in large, extended family groups. Is this a positive or negative trend?

I think that it was a positive. Because we could extended when in our big family have many people and it gonna be hard when it was like about more than 30 person live in a house. It gonna be easier for doing work when we live in a small family. When we live in a small family we can traveling a lot of place with just about 5 - 9 people. Dont need to do like the whole big family must go together when anyone celebration a party. We can visit another small family in our big family if we have time to visit them. Even it mean that when we extended our big family so we can't talk or meet each other but we can still call and chatting with a lot of apps or websites. When we going and travel a place we just need to buy ticket for about 5 - 9 people in a small family. We don't need to pay to much. But it gonna be bored than in a big family but sometimes in the big family it wasn't be fun than in a small family. When we extended into a small family it gonna be happier when we celebrate a holiday that everyone see each other in a big family. Because after along time we haven't meet each other so it gonna be happier than everyday we meet everyone and it gonna be bored. I think that we should extended into a small family.
