The ACA commissioned a chiropractic consultant,
Christine Goertz, DC, PhD, to orchestrate the 2000
American Chiropractic Association Statistical Survey,
which was conducted over the first six months of the
year 2000. Doctors were asked to report information
pertaining to the last full year in which they had data.
Approximately 71 percent of respondents chose to
report for 1999.
The remainder reported for the last
half of 1999 and the first half of 2000. As there were no
significant differences between the figures presented in
both reporting periods, the data were pooled. The sur-
vey was sent to a national randomly selected sample of
4,000 ACA members and 1,000 non-members obtained
from ACA databases. The methodology used to draw
the sample is consistent with that used in 1999, and it
includes doctors of chiropractic who have been in clini-
cal practice for less than five years.
An overall response
rate of 30 percent was achieved.
Following is a summary of demographic, practice, man-
aged care, and income information obtained from the
2000 ACA Professional Survey.
For the first time, it is possible to make a direct histori-
cal comparison between a current ACA professional
survey and a previous effort.
For this reason, historical
data from 1997 are occasionally included for interest.
Gender and Age and Years in Practice
Approximately 86 percent of respondents were male.
This figure is slightly lower than that reported in 1997,
but consistent with what has been reported in previous
The average age of respondents was 45
The average length of time spent in chiropractic
practice was 17 years, with 10 percent of respondents in
practice for four years or less and 10 percent in practice
for 30 years or more.
Approximately 75 percent of respondents hold a
Bachelor’s degree in addition to a Doctor of
Chiropractic degree. Less than four percent reported
having any of the following degrees: Master’s, PhD,
MD, PT, or DO.
General Practice Characteristics
Location of Practice
The majority of chiropractic physicians (92 percent)
reported that they practice in one state only.
one-quarter of respondents practice in communities of
between 2,500 and 24,999 people.
While 47 percent of
the DCs practice in communities of less than 50,000, 53
percent are concentrated in communities with more than
Approximately 10 percent of respon-
dents practice in urban areas of more than one million
Most DCs (70 percent) said that they prac-
Sixty-two percent of the surveyed DCs stated that their
communities had “about the right number” of chiroprac-
tors in relation to demand, while 29 percent said that
there were too many, and 9 percent responded that the
community needed more DCs.
These figures are
approximately the same as those found in the ACA’s
1995 and 1997 surveys.
