* 1986-1992 data from Wheatley 1999 , ND=no data
not included in Table 6.1 due to the unclear relationship between Wheatley's
groups 1, 2 and 3 and groups 1, 2 and 3 during this study. Because of methodo-
logical inconsistencies in reporting of deaths between August 1998 and June
1999 data on deaths are not given for either 1998 or 1999.
The population at Padangtegal underwent a 40 percent increase in size
between 1998 and 2002, with 80 percent of this growth occurring since 2000
( Table 6.1 ). This increase in population size was not equally distributed across
the three groups in the population. The smallest group, group 1, increased by
35.5 percent between 1998 and 2002, and underwent a transition from a one-
adult male group to a multi-adult male group (one adult male to three adult
males). Group 2, the largest group, increased by 65 percent, and group 3 (the
largest group in 1998) only increased by 10.5 percent.
Table 6.2 shows the age and sex class distribution for the total popula-
tion for 1986, 1990-1992 and 1998-2002. During the 1990-1992 period
the number of adult males increased by 27 percent, adult females by 31
percent, and immatures by 25 percent. During the 1998-2002 period adult
males increased by 34 percent, adult females by 46 percent, and immatures
by 37 percent.
