be.seen. There are still many villages that suffer a
shortage of drinking water at the last stage of the almost
half-year-long dry season. Figure 2 indicates that areas
along major rivers and mountainous regions, where water
is more readily available, are the first to get a piped
supply.
4.2 Economic Conditions
The economic growth of the Bangkok metropolitan area
has engendered an increase in employment opportunities
and that has accelerated the exodus of labor from
Northeast Thailand. Figure 3 shows the percentage of
households in which one or more members engage in
work outside the fambon, which includes around 10
villages. The survey also covers the major destination
of migrant workers, revealing that about 8096 of them
work in the Bangkok metropolitan area.
The increase in opportunities to earn cash income has
contributed to a rise in ownership of vehicles. Figure 4,
Figure 5, and Figure 6 show the distribution of bicycles,
motorcycles, and pick-up trucks, respectively. The data
on motorcycles and pick-up trucks suggest that the
popularity of motorized vehicles is related to road
conditions, trading posts, and local cities. And a
relationship with a topographic conditions can be
discerned in the distribution of bicycles and motorcycles.
4.3 Hygiene Conditions
Hygiene conditions are also improved. Figure 7, Figure
8, and Figure 9 show the number of patients with
dysentery, malaria, and measles, respectively, in the
previous two years. These show a clear decline in the
incidence of new cases.
In the case of malaria, Figure 8 shows the concentration
of new cases along the Mae Khong River and along the
border with Cambodia. Formerly, it was not rare In the
