cannot use vector in class method?

I have a 'god' class and a 'person' class that both derive from the 'universal' class. The universal class does things like set their names and ages (simple stuff). I am trying to make a 'god' method that creates new people by using a vector. This is how I usually use my vectors:

Code:

---

typedef vector<type*> TypeVector;
TypeVector NewVector;
NewVector.push_back(new type);

---

I want to have basically the same thing in my createpeople method in the god class

Code:

---

        void createpeople(int people) {
                typedef vector<person*> PersonVector;
                PersonVector People;

                cout << endl
                << "Creating people" << endl;
                for(x = 0; x < people; x++)
                        People.push_back(new person);
                godspeople = people;
 }

---

it says that person is an undeclared identifier
