What is home?

They say your home is where your heart is. Then my heart would be broken anyway. Researchers had real problems trying to determine what is home for all people. There is always a certain error. When applying questionnaries for a census, they had to operationalise the concept of home. Is it the place where you sleep? Then can some people who travel all the time call the hotel or tent home? Is that where we should look for them when we are doing a census? Another option is to consider home the place where we keep our things. But some people live in one place with a partner and keep their stuff in some privately owned place. Home can also be the place where we spend most of our private time. But then for some people the park, the coffeeshop or the gym may be considered to be home. I never defined what home is for me. But I can only find one thing: it's the place where, at least for a while, you always go back when nothing is the best thing to do.
