This '''subtemplate of {{Tl|Infobox settlement}}''' displays a metric/imperial pair of population density values for a line in the main infobox.

== Usage ==
<syntaxhighlight lang="wikitext">
{{Infobox settlement/densdisp
| /km2 = ''auto'' or population density per [[Square kilometre|km2]] (via ''population_density_km2'' and others)
| /sqmi = ''auto'' or population density per [[sqmi]] (via ''population_density_sq_mi'' and others)
| pop = population (via ''population_total'' and others)
| km2 = area in square kilometres (via ''area_total_km2'' and others)
| sqmi = area in square miles (via ''area_total_sq_mi'' and others)
| ha = area in [[hectare]]s (via ''area_total_ha'' and others)
| acre = area in [[acre]]s (via ''area_total_acre'' and others)
| dunam = area in [[dunam]]s (via ''area_total_dunam'' and others)
| pref = preference to display /km2 or /sqmi (via ''unit_pref'')
| name = name of country (via ''subdivision_name'')
}}
</syntaxhighlight>

==Examples==
=== density as auto ===
As shown in the following examples, this template calculates the density if all three of the following conditions are met: /km2 (or /sqmi) is set to auto, a number if given for population, and a number is given for area. It also strips any formatting from the numbers, such as population with commas in the examples, which would otherwise cause an error in the calculation (see [[mw:Help:Magic words#Formatting]]).
