San Diego is roughly 38% more expensive overall, and housing is doing almost all of the work: a one-bedroom runs $950 in Birmingham against $2,400 in San Diego.
Housing does most of the damage
Housing is the reason two metros differ at all. Everything else — groceries, a haircut, a phone plan — varies far less than rent does. A one-bedroom runs about $950 a month in Birmingham and $2,400 in San Diego — $1,450 a month apart, or $17,400 a year.
If you plan to buy rather than rent, the numbers move further apart: median prices of $220,000 and $900,000 mean a difference of about $136,000 in up-front cash at 20% down, plus whatever the property tax spread between Alabama and California adds annually.
The price-to-rent ratios diverge enough to change the buy-versus-rent answer: about 19 in Birmingham versus 31 in San Diego. Under about 15 the math favours owning; over about 20 it favours renting and putting the down payment to work elsewhere. Which means the right answer can genuinely be to buy in one and rent in the other.
Taxes the index leaves out
There is a city-level tax to account for as well: Birmingham charges about 1.00% local income tax, while San Diego charges none. On $100,000 that is roughly $1,000 a year, deducted before you ever see it and easy to miss when comparing two offers.
Getting around
Birmingham is effectively car-dependent; San Diego is served by limited transit.
Work, weather, and what else is different
Birmingham is a mid-size metro of about 1.2M and roughly flat; San Diego is a large metro of about 3.3M and growing steadily.
The two economies have little in common. Birmingham runs on healthcare/medical research, banking, manufacturing — University of Alabama at Birmingham (UAB) and Regions Financial among the larger employers — while San Diego runs on military/defense, biotech, tourism, with US Navy and Qualcomm. Moving between them usually means changing industry as well as address, so line up work first.
Climate belongs in the comparison, not as a footnote. Birmingham: Humid subtropical: January highs near 53°F/lows 34°F, July highs near 91°F/lows 71°F, humid summers. San Diego: Mediterranean climate with mild winters near 50°F lows and mild summers with July highs near 76°F, rarely extreme in either direction.
Birmingham levies a 1% occupational tax on wages earned within city limits, on top of Alabama's state income tax; UAB is by far the metro's largest employer. Among the most expensive housing markets in the country despite no local income tax; mild year-round climate is a major draw offsetting high housing cost.
The index behind the headline ratio is BEA Regional Price Parity data; rents and home prices are market figures, and tax rates are as published by each state and city. How these are compiled and updated.
