What are the reasons that Mumbai is so croudy place?

Mumbai is normally called a dream city and therefore people are coming here to fulfill their dreams, thats why its getting crowded.

Because
It is the destination of most number of job seekers
It is the city of bollywood.Many come to fulfill their wishes of acting in bollywood.
it is the cricket capital of India, the most beloved game of Indian masses.
it was the place where Gandhiji spent a lot of time during his struggle for freedom.
AND FINALLY BECAUSE IT IS THE CITY OF DREAMS.

I have not visited Mumbai.But I have heard from people that it is a very crowded city.

The national highway number 3, popularly known as Mumbai-Agra highway, virtually connects southern India with northern India. so it makes it crowdy

Mumbai is a number one destination for thousands of people from all over India to migrate to! Every day hundreds of people come to Mumbai in search of jobs making it an extremely crowded place!

Yes its true all reasons I am in Mumbai because of job so that is for other also.

Population is increasing day by day. Space is reducing day by day. Government is trying many solutions to free traffic and also implemented like metro,mini tram etc. People come here,as they believe their dream place.

It has openings in almost all industries starting from technology to entertainment.It may be one of the reasons why mumbai is crowded.

Mumbai being the economic capital of India many business are going there and people like to settle there hence.

Due to many job oppurtunities it is main target for job seekers and is also capital city so obviously populated :)

I think Govt. will have to undertake systematic crowd reducing majors to deal with the crowd problem. For example Bandra-Worli sea link reduces the traffic on main road.Similarly off-track dwelling places will have to be thought of.

There is one station Dadar its is so croudy station you can not walk easily.

As there are lot of job opportunities, many opportunities mumbai is croudy place.

As said by Kavita, its is a dream city since long and so it has always attracted people from all over the country.
