If you're planning to have Sherriff "Spellbomb" Bob, Deputy Sidekick and a couple of "uncredited" redshirts (who most likely would also be responsible for one or two other neighboring villages as well), you should probably up the size of the population to at least a hundred adults, a lot of whom the pcs will likely never seriously interact with. Having only 33 adults in the village would end up making it little more than a handful of huts that probably tends a communal garden plot of no more than an acre or two.
- If the village has a public house, that's likely at least three or four people just to run that - plus the six guards, that's already ten people...
- Any sort of general store where the npcs or party could buy supplies would require another person (and probably their family) to run it. There's a couple more...
- Unless one of the farmers is just considered the unofficial leader of the community, there will be some sort of official leader or headman, possibly with an assistant or second...
- If they're providing food to the nearest city, unless each farmer is transporting their crops to the city on their own, they'll probably have at least one centralized building to store all that food until the next shipment to the city and probably will have at least one or two more people involved in that on a full-time basis.
- If any of the local farmers are growing grains, there's probably a miller (and family) as well.
That's close to half your original population figures right there.
