I believe happiness can be measured and promoted to a certain point, obviously you can’t just make a person happy by saying a certain thing to them or by asking a question. Everyone has their own opinion to what happiness means and what to do to make themselves happy. People will be happy if they see change in their community, the government knows what goes on and what people are going through everyday. If they really wanted people to be happy they would just act on it not ask a question on a census. A lot of people don’t even read all the questions through they just skip around or put whatever to get it over with.
Another thing is that honestly only you can make yourself happy because you have your own definition to it and you can change things to better yourself and your life and what you do. The government can only do so much to help a person be happy.
