Thanks.
About city sizes I looked them up (for around 1936)
here. Surprisingly New Orleans has grown very slowly, or in some periods actually shrunk. The top 5 cities (in 1936) are:
1. New Orleans, Louisiana: 494,500
2. Havana, Cuba: 403,000
3. Houston, Texas: 384,500
4. Louisville, Kentucky: 319,100
5. Jacksonville, Sonora: 305,400
'Jacksonville, Sonora' is really Culiacán in Mexico, which in OTL only had about 22,000 people but in this AAR is the most important Confederate port on the Pacific so is a good deal larger.
Like I said Dixie is very much a nation of large towns and small cities which gives it a more conservative, less comopolitan air than the North with it's metropoli. The old landed gentry are no longer quite as powerful as they were in 1860, but they still have a great deal of clout and social influence. Chivalry and honour are concepts alive and well in the Confederacy and many Southerners have quite a low opinion of the (in their opinion) rude, boorish, materialistic, stressed, self centred Northeners. In the United States a typical Confederate politician would be called 'long winded'. In Dixie he is an 'orator'.
