1. A method of surveying a target population, the method comprising:

  • (A) fielding a survey instrument to members in a sample population of said target population, wherein individual members in the sample population are selected from said target population such that a distribution of members in the sample population that start said survey instrument provides a probability sampling of said target population for at least one stratification variable, wherein a distribution of the target population with respect to the at least one stratification variable is known;

    (B) identifying a qualifying population from said sample population, wherein each member in said qualifying population qualifies for said survey instrument based on a response to one or more screener questions in the survey instrument; and

    (C) determining a total number of members within the target population that said qualifying population represents based on a comparison of (i) the distribution of the qualifying population with respect to the at least one stratification variable and (ii) the distribution of the target population with respect to the at least one stratification variable.
