What does influx mean?
An influx is the arrival of a large number of people, animals, objects, money, or ideas into a particular place, group, or system. The word often implies that the arrivals are sudden, substantial, or noteworthy, although it does not necessarily indicate that they are unwelcome. It is commonly used with abstract and concrete subjects, as in an influx of tourists, an influx of investment, or an influx of new ideas. In journalism and formal writing, influx frequently describes a rapid change in a community, institution, or market, such as a sharp influx of refugees or a steady influx of applicants. Although “inflow” can be used in similar contexts, “influx” gives a stronger impression of a notable concentration or movement of people or things arriving together. The word is standard in both British and American English.
