      Probability sampling (a term due to Deming, [Deming]) is a sampling porcess that utilizes some form of random selection. In probability sampling, each unit is drawn with known probability, [Yamane, p3] or has a nonzero chance of being selected in the sample. [Raj, p10] Such samples are usually selected with the help of random numbers.

For some basic models, balanced sampling can be shown to be an optimal sampling design. Emphasis is placed on new spatial sampling methods and their related models.

      For a probability sample, every operation in the population has a chance to be in the survey. The probability survey will estimate the same farm characteristics as the census but will only question a small fraction of the population chosen by chance. With only a small part of the population chosen for a probability survey, each interview is
