There is a strong positive correlation (r = 0.70) between the economic freedom and personal (social) freedom of countries. Both are also moderately positively correlated with happiness (economic r = 0.55, personal r = 0.67).
Countries on the bubble chart, showing the economic and personal axes, with happiness indicated by green high through to red (colour-free version below), and the size of bubbles based on population. Some key countries are indicated.
Both economic and social freedom are important, and related, so a good strategy would be to try and increase both.
