Learn Swedish: Statistiken visar att andelen sysselsatta är hög. - The statistics show that the proportion of employed is high.

In Swedish, statistik is an uncountable, singular noun. That's why it takes the singular definite suffix -en (statistiken), even though we translate it as the plural "the statistics" in English. If you need to refer to a single statistical fact, you would use a word like en siffra (a figure) or en uppgift (a piece of data).

Why is there no Swedish word for "of" in andelen sysselsatta (the proportion of employed)?

In Swedish, when expressing a quantity, amount, or proportion of something, you usually just place the words side-by-side without a preposition like av. This is the exact same rule you use for phrases like en kopp kaffe (a cup of coffee) or ett antal böcker (a number of books).

What kind of word is sysselsatta, and why does it end in -a?

Sysselsatta is the past participle of the verb sysselsätta (to occupy/employ). In this sentence, it is functioning as a plural noun meaning "employed people". Because it refers to a plural group, the participle takes the plural ending -a.

This lesson focuses on varav (of which/whom). How could we continue this sentence using varav?

You can use varav to describe a subset of the employed people right after this clause. For example: Statistiken visar att andelen sysselsatta är hög, varav de flesta arbetar heltid (The statistics show that the proportion of employed is high, of whom most work full time).
