    Actually, there are three main components of dust: first, dead skin cells, second, the dried feces and dessicated corpses of dust mites (lovely thought, eh? When people develop a house-dust allergy, this is usually the component they are reacting to), and the last component by volume is tiny fibers shed by clothing -- cotton is bad for this, and jeans are the worst. This is for ordinary house dust. (Incidentally, dust mites are not generally visible, except with a microscope; they are 200-300 microns long, they eat dead skin cells and live in bedding, carpets and soft furnishings. Always. Trust me on this, anything a year old or more has a good population of them.)

    In the case of a new basement, on the other hand, the primary component of dust is likely to be the obvious: concrete. Elsewhere in a brand-new house plaster and plasterboard both "shed" copiously over the first few weeks.

    And outdoor dust is fine particles of soil and stone dust (composition dependent on location and prevailing winds), with a hefty component of pollen and other plant material.

    So it does depend on where you are.

    I am very sorry to say that dust is not made of mainly of dead skin... (if so then your bedroom would contain the most dust)

    Dust is mostly made up of the small particles of dirt, wood, fibres etc. The normal stuff you would find in your local enviroment. Dust is dust because the particles are small enough to be carried in the air.

    Dont forget lead. If your home was built before 1979 it likley has lead in the dust.
    Lets say your house was built in 1940.
    Back then lead was used to make the paint more durable and last longer. Sometimes paint was 1/2 lead(50%) and most homes were painted with it. At some point, say in 1950 or 1960 the owners decided to repaint the house. Maybe the old paint was peeling or maybe they just wanted a new color. So they scraped and sanded the old paint creating huge amounts of dust in and outside of the home. Then repainted with yu guessed it lead paint. lol This was repeated several times over the years and still occurs today. Although today paint has no lead in it.
    but dust is created when old paint is sanded or scraped. Not to mention deposits in soil from leaded gasoline that remains even though it has been banned. So if you live near a busy road or in an older home you have plenty of lead in your house hold dust. I recommend taking off your shoes before entering the home, don't sweep. Use a wet mop or a heppa vacuum that is rated 99.97 micron.

    Dust is made of just about everything. Household dust is composed primarily of
    things like human skin and hair, waxes, pollen, mold, fungi, lichen, tiny
    particles of wood, paint, fibers from fabrics such as wool, nylon, rayon,
    acrylic (and in the disco '70s lots and lots of polyester), foam rubber, sheet
    rock, plant and vegetable matter, insect parts, and of course every form of
    pollution such as auto and industrial emissions, heavy hydrocarbon waste from
    your oil or gas heater, even tiny bits of metal debris from door hinges or any
    place where metal and friction meet, lots of food waste, and loads of paper
    fiber...
