Pasadena Population: 137,122
Altadena Population: 42,777
Personally speaking I do not feel like Pasadena or Altadena are very crowded cities. Yes during the rush hours there are more than the average number of people who live in these cities but that is because people from all over come out to work mostly in Pasadena. Pasadena definitely has more foot and car traffic than Altadena because Pasadena is more of a city with buildings and large shopping hot spots.
