Factory pattern C# with autofac

Question

I would like to adapt the factory pattern (from wikipedia) using autofac :

/IVSR:Factory Pattern
//Empty vocabulary of Actual object
public interface IPeople
{
    string GetName();
}

public class Villagers : IPeople
{
    #region IPeople Members

    public string GetName()
    {
        return "Village Guy";
    }

    #endregion
}

public class CityPeople : IPeople
{
    #region IPeople Members

    public string GetName()
    {
        return "City Guy";
    }

    #endregion
}

public enum PeopleType
{
    RURAL,
    URBAN
}

/// <summary>
/// Implementation of Factory - Used to create objects
/// </summary>
public class Factory
{
    public IPeople GetPeople(PeopleType type)
    {
        IPeople people = null;
        switch (type)
        {
            case PeopleType.RURAL :
                people = new Villagers();
                break;
            case PeopleType.URBAN:
                people = new CityPeople();
                break;
            default:
                break;
        }
        return people;
    }
}

In addition, classes implementing IPeople should benefits of dependency injection, for example CityPeople constructor should have a IRepository injected, Villagers should have an IService injected, and so on ...

How can I do that ?

Thanks in advance for your answers
