Odds ratios as a measure of disproportionate treatment: application to jury venires

Odds ratios have several advantages over other methods of measuring the degree of under-representation of cognizable classes of potential jurors. In particular, its advantage over comparative disparity is that it does not measure the extent of under-representation of some groups against an aggregate that includes the very group in question. Odds ratios in jury analysis are directly interpretable as the factor by which one's probability of being on the jury is advanced or diminished by membership in a specified group.
