The number of Mormon missionaries entering the proselytizing ranks has gone up more than 40 percent since age requirements changed last year. But the number of convert baptisms is pretty much flat.

On Monday at 12:15 p.m., authors Matt Martinich and David Stewart along with Tribune religion reporter Peggy Fletcher Stack join Jennifer Napier-Pearce to talk about why and how demographics and geography play into LDS missionary efforts.
