Breakdown of Die Bevölkerung in der Stadt ist jung.
Questions & Answers about Die Bevölkerung in der Stadt ist jung.
The preposition in is a Wechselpräposition (two-way preposition).
• When it indicates location (answers “Where?”), it takes the dative case.
• When it indicates direction or movement (answers “Where to?”), it takes the accusative.
Here we describe a location (“in the city”), so we use dative. Stadt is feminine, and the feminine dative article is der, giving in der Stadt.
German commas separate clauses (especially subordinate or relative clauses) or list items.
This sentence is a single main clause: subject (Die Bevölkerung in der Stadt), verb (ist), predicate (jung). There’s no subordinate clause or enumeration, so no comma is needed.
Could I start the sentence with In der Stadt?
For example: In der Stadt ist die Bevölkerung jung?
Yes. German follows the verb-second (V2) rule. If you front In der Stadt for emphasis, the verb ist still occupies the second position:
“In der Stadt ist die Bevölkerung jung.”
The meaning stays the same, but you place a bit more focus on the location.
• Bevölkerung refers to the population as a whole, a collective concept.
• Einwohner (plural) refers to the individual inhabitants or residents.
So die Bevölkerung der Stadt = “the city’s population,” whereas die Einwohner der Stadt = “the city’s inhabitants.”
