of the Data
2.3-2.7 and 4.5 and
Figures 3-7 show trends in State admission rates. Data were not submitted
for one or more years in some States because of changes to their data
collection systems. These States were: Arizona (1994-1997); Indiana
(1997); Kentucky (1994-1996); Mississippi (1994); West Virginia (1994
and 1997-1998); and Wyoming (1995-1996).
In three States, significant changes in the facilities reporting to TEDS
from 1994-1999 resulted in changes in the number of admissions large enough
to influence trends. For these States, rates are not indicated on Figures
3-7 for the years affected: Texas (1994-1995), Virginia (1996-1999), and
North Carolina (1999). The actual data reported, however, are included
in all tables.
Finally, half-year data only were available for Nebraska and Ohio (1999)
and for West Virginia (1996). Tables 2.3-2.7
and 4.5-4.8 and Figures 3-7
include projected rates based on these half-year data. These projected
numbers and rates are not included in other tables.
