ling venues. Australian data suggests that gambling spending <strong>and</strong> participation<br />
frequency increases as the number <strong>of</strong> slot machines in an area increases [124].<br />
In the USA, it has been found that the prevalence <strong>of</strong> pathological gambling was<br />
two times higher among respondents living within 50 miles <strong>of</strong> a major gambling<br />
venue [125 Ch. 5 ]. A similar finding is that living close to casinos predicts gambling<br />
problems in adult males [126]. Using census data, another American study showed<br />
a positive relation between neighborhood disadvantage <strong>and</strong> frequency <strong>of</strong> gambling<br />
<strong>and</strong> problem/pathological gambling [127]. This relation was interpreted to mean<br />
that “the ecology <strong>of</strong> disadvantaged neighborhoods promotes gambling pathology,<br />
<strong>and</strong> that availability <strong>of</strong> gambling opportunities promotes gambling participation<br />
<strong>and</strong> pathology” (p. 405). It was pointed out, however, that “individual traits have a<br />
stronger relationship to gambling pathology than geographic factors” (p. 422).<br />
In California, no relation was found between distance to gambling venues <strong>and</strong><br />
rates <strong>of</strong> problem gambling, probably because <strong>of</strong> the high density <strong>and</strong> relatively even<br />
distribution in geographical space <strong>of</strong> such venues [128]. A study conducted in Louisiana<br />
showed a slight but significant correlation at parish level between the percapita<br />
spending on video-poker machines <strong>and</strong> the number <strong>of</strong> Gambler Anonymous<br />
meetings [129]. However, no correlation was found between the number <strong>of</strong> such<br />
meetings <strong>and</strong> the number <strong>of</strong> machines or the number <strong>of</strong> machine establishments per<br />
capita. A Canadian study found that the prevalence <strong>of</strong> problem gambling was associated<br />
with numerous demographic factors, such as substance abuse <strong>and</strong> physical<br />
health status. Proximity to gambling venues, however, showed only a weak association<br />
[130].<br />
While the studies mentioned thus far have concerned relatively small geographical<br />
units, there are investigations on a larger scale. One such study [131], which compared<br />
US states, observed that the rate <strong>of</strong> problem gambling was significantly higher<br />
in states where legal gambling had been available for more than 20 years, compared<br />
to states where it had been available for less than 10 years. It was concluded that this<br />
supports the contention that increased availability <strong>of</strong> gambling results in an increase<br />
<strong>of</strong> gambling-related problems.<br />
A second large-scale study [132] concerned both US states <strong>and</strong> counties <strong>and</strong> used<br />
a Regional Exposure Model (REM), in which gambling is viewed as a public health<br />
toxin [133] that causes harm to some people if exposure is high enough. The REM<br />
model includes variables <strong>of</strong> dose, potency <strong>and</strong> duration <strong>of</strong> exposure to gambling,<br />
which are used to compute a Regional Index <strong>of</strong> <strong>Gambling</strong> Exposure (RIGE). Comparing<br />
RIGE values to problem gambling prevalence data at the county level, a certain<br />
measure <strong>of</strong> positive correlation was found. The authors intend to complement<br />
the REM model with a Personal Exposure Model (PEM), including exposure to<br />
gambling on the individual level, e.g. parental gambling, household gambling, <strong>and</strong><br />
being employed in the gaming industry.<br />
In sum, geographical mapping <strong>and</strong> analysis promises to add valuable knowledge<br />
about the connection between <strong>social</strong> factors, the availability <strong>of</strong> gambling <strong>and</strong> the<br />
prevalence <strong>of</strong> problem gambling. However, the link between availability <strong>and</strong> prob-<br />
