This subtemplate of {{Infobox settlement}} displays a metric/imperial pair of population density values for a line in the main infobox.
Usage
{{Infobox settlement/densdisp
| /km2 = auto or population density per 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 hectares (via area_total_ha and others)
| acre = area in acres (via area_total_acre and others)
| dunam = area in dunams (via area_total_dunam and others)
| pref = preference to display /km2 or /sqmi (via unit_pref)
| name = name of country (via subdivision_name)
}}
Examples of 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).

Examples of missing population or area
As shown in the following examples, this template outputs nothing if density = auto, but either population or area is missing.
