Will Tabular Data Work for This?

Hello, all. I am undertaking a research project utilizing tabular data. I am planning to take a lot of information about cities around the world, and putting them in a Excel sheet. I will label them with scores, one each, concerning happiness. Is it possible to use this model to predict the happiness score of another place? And even more specifically, can I use this to identify the most significant factors in happiness in a country? I’m new to this, but I would really, REALLY, appreciate help on this. thank you so much!
