Series P5 Estimates:  This is a reference to a scheme for measuring Poverty in 5 levels, adopted at the University of Texas, Medical Branch (UTMB).  The lowest level includes all people living between no income and 100% of the federally defined poverty level.  Levels two and three include people living between 100-199% and 200-299% of poverty, respectively.  Level four includes those people living at or above 300% of the poverty level.  Finally, the fifth level includes all those living at an undefined level of poverty.  The undefined are primarily institutionalized and group quartered individuals.*2

Serious mental illness (SMI): is a term defined by Federal regulations that generally applies to mental disorders that interfere with some area of social functioning.*3 approximately 5.4% of US adults (Kessler et al., 1996).  

Severe and Persistent Mental Illness (SPMI): About half of those with SMI (or 2.6% of US adults) were identified as being even more seriously affected, that is, by having “severe and persistent” mental illness (SPMI) (NAMHC, 1993; Kessler et al., 1996).
