Usage tips
Word family
'Die Häufung' (accumulation) belongs to the word family of 'der Haufen' (a pile) and the verb 'häufen' (to accumulate). The ending '-ung' turns it into a noun that describes the process or result of an accumulation.
EXAMPLE
Die Polizei untersucht die Häufung von Einbrüchen in der Nachbarschaft.
The police are investigating the accumulation of burglaries in the neighborhood.
Use with genitive
To specify what is accumulating, the genitive or the preposition 'von' + dative is often used. The genitive is more common in written language.
EXAMPLE
Die Häufung der Fehler im Text ist besorgniserregend.
The accumulation of errors in the text is concerning.
Typical collocations
The word is often used for negative or neutral things, for example a 'Häufung von Problemen' (accumulation of problems), 'von Unfällen' (of accidents), 'von Zufällen' (of coincidences), or 'von Krankheitsfällen' (of cases of illness).
EXAMPLE
Ist das nur eine Häufung von Zufällen oder steckt mehr dahinter?
Is that just an accumulation of coincidences, or is there more behind it?

'Häufung' (accumulation) is used mainly in formal, official, or scientific contexts, for example in news reports, reports, or analyses.
EXAMPLE

Häufung vs Verteilung
distribution
'die Verteilung' and 'die Häufung' can both describe where or how often something occurs. 'die Verteilung' asks neutrally: How is something distributed across places, times, or groups? 'die Häufung', on the other hand, says that something occurs especially often in one place or during one period of time. They can be confused because both appear in statistics or reports. The difference is important: a distribution can be even or uneven; an accumulation always means a clear concentration.
Häufung
In der Nachbarschaft gibt es eine Häufung von Einbrüchen.
There is a cluster of burglaries in the neighborhood.
Verteilung
Die Karte zeigt die Verteilung der Hausärzte in der Region.
