Look, I love nothing more than watching The Walking Dead , but after seeing the following question on 4chan , I don’t know what to think.
So, let's say the population of the United States is about 300,000,000.
The census bureau has the number at about 313.9 million.

And let's be generous and say that 99% of the population is infected by the zombie outbreak.
So then it's safe to assume that there are about 297 million people infected and 3 million survivors.
Now let's assume that Rick's group isn't the only group left out of the 3 million survivors. If each group has about 20 people in them, then that leaves us with with 150,000 groups.
3,000,000 / 20 = 150,000.
