Though perhaps they're not analogous, this question was in part prompted by consideration of the Black Panthers and their community efforts (such as the famous "Free Breakfast for Children"). Did any of the republican groups (especially ones more militant in contrast to other nationalists) develop or attempt anything similar for the Catholics?
edit: I don't know why I wrote "/social", that's not the correct term haha
The short answer: No. First, the Black Panthers and the IRA are not analogous (though some other Nationalist groups may be but those are outside my area). This is not to say that that such programs may not have been implemented but that I have never come across any references to any. Sinn Fein has gradually expanded beyond a straight platform calling for a United Ireland and have begun to look at more international and local affairs (Wind Turbines, education funding) but these fall within the 20 year rule and are really just recent developments outside of the Troubles.
The Provisional IRA, instead of "community/social program", focused on military and policing actions. They sought to protect the Nationalist and Republican communities from British/Unionist/Protestant attacks. Also, they utilized squads to administer punishment to Nationalists/Catholics that dealt drugs, stole, fraternized with the wrong people.
If programs like "Free Breakfast for Children" existed during the Troubles then they are new to me. Hopefully someone else with that knowledge can help out.
