The population density of Europe, as a whole, is 143 people per square mile. This makes Europe the second most densely populated continent in the world, with the first place being occupied bu Asia, so we can say that Europe is a densely populated continent as a whole.
It has to be taken in notice that Europe is a continent that has an aging population, the fertility rate is very low, and the life expectancy is high. Interestingly enough, even though there's only three countries in the whole continent that have a positive fertility rate, the population of the continent is still growing, slowly, by 0.3% annually, but it is growing. The growth is mainly because of the migrants, mainly from the Middle East and Africa, and apart from increasing the number of the population with their entry, they also tend to have a high fertility rate.
When a cyclone's strongest winds do not exceed 61 kilometers (38 miles) per hour, it is called a tropical depression
Tropical cyclones are classified based on their wind speed. When the fastest sustained winds does not exceed 38 miles per hour (61 km per hour), it is called a tropical depression.
If the fastest wind is greater than 38 miles per hour (61 km per hour), it is called a tropical storm.
However, if the maximum sustained wind speed reaches 74 mile per hour (119 km per hour) it is referred to as a hurricane.
