Not quicker really. Most cities are growing far more slowly than their boom years, whether those were 2005 or 1905. Industrialization was a seismic shift in the 1800s. The adoption of railroads, rail transit, and cars created massive urban shifts in short periods of time. The suburbanization of retail, white flight, urban renewal, and the freeway-building era we all massive connected shifts that peaked in a fairly short period. Today the shift back to cities and mixed-use has been going on for decades.
