(Why “ECON” in all caps?)
People with particular expertise in statistics and data analysis are always needed, so if that’s your strength, then skew your education that way. You can combine statistics with economics

or combine stats with public policy

Of course, you can do a double-major or major+minor - you don’t necessarily need a school with an interdisciplinary major, so long as there are strong offerings in economics, math/statistics, and poli sci/public policy to cover your areas of interest. Flexibility is good, because you won’t really know what direction you want to go in with all of this until you have some experience in these subjects at the college level. Many econ departments have a quantitative track with heavier math requirements than the “regular” econ track, and that would be a good default plan for you to start with, as you could flex from there. (i.e. change to a math major with an econ minor if you preferred the math focus, or add a poli sci minor, or… anything you want.) https://ase.tufts.edu/economics/undergrad/majorQuant.htm
Also consider how much computing and “big data” focus you might want to include. The UMichigan stats department is a good place to look at the different variations on the theme of stats - data science, informatics, statistics, applied statistics… any of these can be combined with economics, political science, and other social sciences. https://lsa.umich.edu/stats/undergraduate-students/undergraduate-programs.html
