The level of crowdedness in India i feel like would be the most because it is a smaller country, but has the second biggest population in it. Also China has a huge population, but a larger land mass then India has. Then China also has most of its population in the south east portion, so in that area it is a lot more crowded then almost any other place on earth. On the other hand the United States is not compacted the population is spread out. The only small cluster of people would be in the north eastern part of the United States which is growing but not totally crowded yet.
