Is the US or Mexico more densely populated?

Answer 1

Mexico is more densely populated with 60 people per square kilometer (155 people per sq mi) vs the US' 35 people per sq km (89 people per sq mi). But this is because the United States has much more undeveloped space (i.e: Alaska, almost the size of Mexico itself).

Answer 2

According to the US-Mexico Border Coalition, there are 23 counties directly bordering Mexico, with a total area of 197,014.6 square kilometers (76,067.7 sq mi) and a population of approximately 6,712,445 people (2004). The population density would be of 34.07 people per square kilometer, or 88.24 people per square mile.
