{title:Description}

{pstd}
{cmd:svy: proportion} produces estimates of finite-population proportions for
the categories identified by the values in each variable of {it:varlist} from
survey data; see {helpb proportion} for a description of sample proportions
from nonsurvey data.


{title:Options}

{phang}
{it:svy_options}; see {helpb svy}.

{dlgtab:Model}

{phang}
{opt stdize(varname)}
specifies that the point estimates be adjusted by direct standardization
across the strata identified by {it:varname}.  This option requires the
{opt stdweight()} option.

{phang}
{opt stdweight(varname)}
specifies the weight variable associated with the standard strata identified
in the {opt stdize()} option.  The standardization weights must be constant
within the standard strata.

{phang}
{opt nostdrescale}
prevents the standardization weights from being rescaled within the
{opt over()} groups.  This option requires {opt stdize()} but is ignored if
the {opt over()} option is not specified.

{phang}
{opt nolabel} requests that value labels attached to the variables in
{it:varlist} be ignored.

{phang}
{opt missing} specifies that missing values in {it:varlist} are to be treated
as valid categories, rather than be omitted from the analysis (the default).
