(c) The assignment of a county to a tier shall be based on a ranking of:
(1) Unemployment rate;

(3) Per capita personal income; and
(4) Population change.
(d) The commission shall:

(4) A tier increase approved under this subsection remains in effect until the annual tier rankings are updated under subsection (d) of this section.
