I've done some poking around on this information in Pennsylvania, specifically.
For the most part, there is some geographic dispersion. There are a few tickets that seem to strike in close proximity. You see a lot of people complain on the PA Lottery Facebook page that winners are only in certain counties, but it's based on where tickets sell and Pennsylvania's population is heavily balanced toward specific counties and areas. A rural county nobody lives in isn't going to have that many winners, and that makes complete sense.
From a sheer numbers standpoint, there's actually substantially less jackpot winners in the Philadelphia suburbs than there should be. It depends on what county I live in and where I'm at whether I'd avoid a ticket. If I live in say, Forest County, and a jackpot winner hits in that county, then it's probably safe to say another one will not hit there. Another could very well strike in Bucks County. I'm willing to bet at least 1 or more of the 4 remaining $5,000,000 top prizes will be found in either Philadelphia or its suburbs.
There are certain counties that seem to have a larger percentage of jackpot winners than they should, but it seems the lottery is more popular in those counties. It seems it's just less popular in general in the Philadelphia suburbs. The one caveat is that other than for $1,000,000 top prizes and above, the Lottery data shown in reports is only of the county the person claiming it lives in, not where the ticket is sold. This means tickets will show as out-of-state when they were obviously bought within PA, and there's a great chance someone buying a ticket isn't necessarily buying it in their county. I've bought scratch-offs in almost every corner of PA at some point.
One of the questions I've seen come up here is to figure out how many tickets are available in each game. I've got a formula for that. It's not as exact as I'd like for a few reasons.
1) It doesn't count I don't believe if someone throws away the ticket or holds on to it but never claims it.
2) Some of the odds for lesser prizes are still steep. I wish PA had like MD does with the exact number of remaining prizes down to the smallest one.
So how do I calculate this?
You take the 4th highest prize, the 5th highest prize, and the 6th highest prize. You multiply each of those by the odds given for finding that prize. You then average those 3 numbers together.
From the Lottery's sheets on each game, we know how many overall tickets there are, unless they add additional tickets to a game.
So if we use the $50 $5 Million Money Maker ticket being discussed here,
To win $10,000, it's 1 in 12,000. As of today's update, there's 517 of those still out there.
To win $5,000, it's 1 in 6,000. As of today's update, there's 1,047 of those still out there.
To win $1,000, it's 1 in 279.07. As of today's update, there's still 20,760 of those still out there.
So that gives you anywhere between 5,793,493 and 6,282,000 tickets of the original 7,200,000. That means roughly by my count, 84.63% of the tickets remain, 15.37% of them have been sold so far.
I've got these numbers on any game still claimable. Don't let the "closed games" thing fool you, I see plenty of supposedly "dead" games still for sale throughout the state, although it's a lot more plentiful for $1, $2 and $3 tickets than at the higher end where sales are typically better. Very few $1, $2 and $3 tickets sell down all that much based on the formula I posted above. I still like $3 tickets myself, the only claimer I've ever found was on a $3 scratch-off ticket back in 2019.
