Chicago

Overview

Chicago is the subject of Homer Hoyt's One Hundred Years of Land Values in Chicago (1933), a doctoral dissertation that reconstructed a century of the city's land values from 1830 to 1933 and documented a recurring rhythm of speculative boom and bust rather than smooth growth. The study traces Chicago's growth from a frontier settlement of a few log huts to a city of 211 square miles and roughly 3.5 million people, with aggregate land values rising from a few thousand dollars to more than $5 billion.[1][2] It remains the founding empirical source behind what this wiki calls the 18-year land cycle, and is frequently cited in Georgist discourse on land speculation and cycles.[3]

Hoyt's Century of Land Values

Hoyt's dissertation, submitted for his Ph.D. in economics at the University of Chicago and published by the University of Chicago Press in 1933 (xxxii + 519 pp.), was the first comprehensive, long-run, data-driven study of land values in a major American city.[1][2] Using 103 maps and 103 data tables, Hoyt assembled comparative data on population density, ethnic settlement patterns, transportation networks, construction activity, employment, mortgage rates, and property sales across comparable American cities.[1][2]

Hoyt's central empirical finding was that Chicago's land-value history divides into a sequence of distinct boom-and-bust episodes rather than continuous appreciation. Secondary sources summarizing the book describe five roughly-defined periods of growth tied to specific historical drivers:[1][2]

1. The canal-land boom of the 1830s — speculative land purchases tied to the construction of the Illinois and Michigan Canal.
2. The railroad era expansion — land values rising with the city's emergence as a rail hub.
3. The post–Civil War boom and the 1871 Great Chicago Fire rebuilding surge — the Fire destroyed a vast swath of the city's central business district in October 1871, and the subsequent rebuilding effort fed a construction and land-value boom.
4. The first-skyscraper and 1893 World's Fair boom — land values inflated in anticipation of the World's Columbian Exposition before collapsing in its aftermath.
5. The post–World War I land boom and Depression-era collapse — a speculative surge in the 1920s that ended in the Great Depression.

The Cycle Episodes and Peak Years

Secondary literature commonly attributes to Hoyt's study a Chicago land-value peak-year list of roughly 1836, 1856, 1872, 1890, and 1925 — an interval of approximately 16–18 years between successive peaks.[1][4] This periodicity is the empirical foundation later writers built on to formulate the 18-year land cycle concept.

[VERIFY: this exact peak-year list against Hoyt's primary text directly; the wiki's own [Progress and the 18.6-Year Cycle](/wiki/progress-18-6-year-cycle/) research page flags the same figures as unverified against a source that could not be directly fetched]

Hoyt's own framing of the underlying mechanism, as excerpted from the book, describes real estate cycles as "the composite effect of the cyclical movements of a series of forces that are to a certain degree independent and yet which communicate impulses to each other in a time sequence" — tracing a sequence of roughly twenty linked events from rising rents through rising land prices, construction booms, overbuilding, foreclosures, and eventual recovery.[2] [VERIFY: confirm this quotation against the primary Internet Archive text directly in a future revision]

The 1871 Great Chicago Fire

The Great Chicago Fire of October 8–10, 1871 destroyed much of the city's central business district and residential areas. In Hoyt's analysis, the Fire and its rebuilding surge constitute one of the major episodes in Chicago's land-value history — the destruction of existing improvements and the massive reconstruction effort that followed drove a boom in land values and construction activity in the post-Fire period.[1][2] The Fire falls within the broader post–Civil War expansion episode that Hoyt identifies as one of his five major growth periods. [VERIFY: the precise role Hoyt assigns to the Fire within his periodization — whether he treats it as a discrete episode or as an accelerant within the broader post-Civil War boom]

Relation to the Georgist Case

Hoyt's study is a historical-empirical source for the premise that land markets exhibit a recurring speculative boom-bust cycle — the phenomenon that the Georgist land-cycle tradition built on. Fred Harrison drew directly on Hoyt's Chicago chronology in The Power in the Land (1983) and Boom Bust (2005) to argue the same land-and-credit rhythm recurs in modern economies, using it to forecast the 2008 financial crisis.[3][5] Fred Foldvary independently reached a similar forecast in 1997, writing that "the next major bust, 18 years after the 1990 downturn, will be around 2008."[6]

It is important to be precise about what this study does not do. Hoyt's dissertation contains no discussion of land value taxation, no policy analysis, and no comparison of speculation under taxed versus untaxed land regimes. Hoyt was not a Georgist and does not argue for land value taxation anywhere in the book.[1][3] The study's real evidentiary contribution to the Georgist case is establishing that the speculative land cycle is a real, long-run, empirically documented historical pattern — the premise the LVT dampens land speculation argument needs in order to have a cycle to dampen — rather than direct evidence of LVT's effect on that cycle.[3]

Limits and Caveats

• Single-city, pre-modern-econometrics study. Hoyt's data and methods reflect 1930s social-science practice: descriptive statistics, maps, and narrative synthesis rather than regression-based causal-inference methods. The findings are a rich historical case study of one city, not a cross-city panel that could isolate land speculation from other drivers of Chicago's growth (railroads, immigration, the Fire, two world fairs, national business cycles).[1]
• No LVT variation to test. Chicago in this period did not have a land value tax regime distinct from ordinary property taxation, so the book cannot speak to how a taxed-land counterfactual would have altered the cycle's amplitude or timing.[1]
• The specific "18-year" periodicity is a later reading of Hoyt's data, not his own headline claim. Hoyt documents a recurring cyclical pattern; the crisp ~18 (or 18.6)-year figure was extracted and popularised chiefly by later writers (Roy Wenzlick, Harrison, Foldvary, Phillip Anderson, Akhil Patel), and the wiki's own Progress and the 18.6-Year Cycle page notes this periodicity claim has not been confirmed by peer-reviewed econometric testing and remains contested.[4] [VERIFY: whether Hoyt's original text itself asserts a fixed ~18-year period, or only documents irregular but recurring booms and busts]
