Is it a physical barrier that opens and closes, or does it just need to provide access from one space to another? And there are a variety of doors – entry, interior, screen, garage, etc.
Even if we narrow our focus to just entry or an exact number of doors, there are still many homes, businesses, and other structures in the world, each with its unique door (or multiple doors).

How Many Doors Are There in The World?
There are n number of doors in the world. The World Health Organization gives out an estimation that there are 7.6 billion people on the planet. According to a study conducted by an experienced mathematician, if the world’s population totals 7 billion, the world’s doors might open to a total of 42 billion. So even if we only count homes, the number of doors is still staggering.
How Many Doors Are in The World Compared to Wheels?
It’s a question that has been bothering humans since the days of the first wheeled carts: how many doors are in the world compared to wheels? The answer, it turns out, is quite complicated.
But, with that in mind, it is estimated that there are approximately 42 billion doors worldwide.
In contrast, there are only about 360 million cars (which typically have four wheels each). That means that, for every car on the planet, there are approximately 117 doors.

How Many Cabinet Doors Are There in The World?
Several factors make it difficult to estimate the number of cabinet doors, including the fact that there is no standard definition of what counts as a cabinet door. As a result, any attempt to estimate the average number of cabinet doors worldwide is likely to be somewhat inaccurate.

This only includes doors for new construction; it does not include replacement doors or doors for commercial buildings. The average home has four exterior and two interior doors, so there is a strong demand for doors each year.
How Are The World Trade Center And The Tallest Revolving Door Correlated?
