```\$title	Assign Households to Deciles

set	h	Households in the survey /h1*h2000/;

parameter	wt(h)	Sample weght associated with this household,
n(h)	Number of individuals in the household,
y(h)	Total household income
ypc(h)	Per-capita household income,
rank(h)	Household rank in per-capita,
pct(h)	Percentile rankings for households;

*	This example is only illustrative:

wt(h) = uniform(0.5,1.5);
n(h) = uniform(1,5);
y(h) = uniform(0,1);

*	First we scale the household statistics to reflect sample weights:

n(h) = n(h) * wt(h);
y(h) = y(h) * wt(h);

*	Then compute per-capita income levels:

ypc(h) = y(h)/n(h);

*	Generate rankings for household based on the basis of
*	per-capita income:

\$libinclude rank ypc h rank

alias (h,hh);
set	ranked(hh,h)	Sorted order;
loop(hh\$(ord(hh)=1),
ranked(hh+(rank(h)-1),h) = yes;
);

set	bug(h)	Check on hh bug;
bug(h) = yes\$(sum(ranked(hh,h),1)<>1);
abort\$card(bug) "Bug in ranking",bug;

parameter	ntot	Total population
nsum	Household count
nt(h)	Total number;

ntot = sum(h,n(h));
nsum = 0;
nt(h) = n(h);
loop(hh\$(ord(hh) <= card(h)),
loop(ranked(hh,h),
nt(h) = nt(h) + nsum;
nsum = nt(h);
);
);

parameter	pct(h)	Percentile;
pct(h) = 100 * nt(h)/ntot;

set	dcl	Household decile assignments
/d10,d20,d30,d40,d50,d60,d70,d80,d90,d100/;

set	hdecile(h,dcl)  Assignment of households to deciles;

hdecile(h,dcl) = yes\$((pct(h) > 100*(ord(dcl)-1)/10)
and (pct(h) <= 100*ord(dcl)/10));
hdecile(h,dcl)\$((pct(h)=0) and (ord(dcl)=1)) = yes;

parameter	fraction	Decile fractions;
fraction(dcl,"Persons")  = sum(hdecile(h,dcl), n(h));
fraction(dcl,"Weight")   = sum(hdecile(h,dcl), wt(h));
fraction(dcl,"NRecord")  = sum(hdecile(h,dcl), 1);
fraction(dcl,"IncomePC") = sum(hdecile(h,dcl), y(h)) /
sum(hdecile(h,dcl), n(h));
display fraction;
