Here are a few good links if you're interested in learning more about how you can get involved:

White House Opportunity Project gathers public data that civic hackers can use to create useful tools or data visualizations - http://opportunity.census.gov/

Find local hackathons and events on this list put together by Code for America - https://www.codeforamerica.org/events/national-day-2016

Finally [full disclosure I work at this one] Bloc and Women Who Code have partnered to create a scholarship where you devote your final Bloc project to a civic hacking project and you get $2000 towards your tuition - http://bit.ly/25zAWRe
