This study extends the Vertical Enclave Model (VEM), a framework I developed in a prior thesis on Indo-Guyanese homeownership patterns in Queens, to Washington Heights, a renter-majority Dominican community where the original model’s ownership-based mechanism does not apply. The resulting renter-adapted variant, the VEM-D, is tested against the enclave’s spatial evolution from 1980 to 1990. Instead of dispersing amid rapid demographic growth, the enclave’s footprint experienced a dual process of local densification and geographic expansion: the historic core in Upper Manhattan maintained an Enclave Density Index far exceeding the statewide average, while density in the adjacent zone nearly doubled over the decade. This trajectory supports cumulative causation theory, showing the enclave matured into a stable, permanent urban fixture rather than a temporary hub. A logistic regression restricted to renter households, with one record per household to avoid duplicating shared household-level outcomes, indicates that residence in higher-EDI borough-year contexts is associated with modestly lower odds of severe rent burden: each additional unit increase in the Enclave Density Index corresponds to roughly 9 percent lower odds, and each additional household member to roughly 14 percent lower odds. Because EDI varies across only four Manhattan/Bronx-by-census-year values, this association is descriptive rather than a person-level or causal protective effect of enclave density. This pattern carries a stratification premium linked to arrival timing: the Settler cohort arriving during the 1980-1990 wave shows roughly 50 percent higher odds of severe burden than early arrivals, a probability-scale gap of about 7.6 percentage points. The VEM-D’s paradox is that the enclave grew rather than dispersed under this migration pressure, but that growth carried a measurable cost that fell disproportionately on the newest arrivals.

These are the plots I created to support my results in my report "Following the Feast"

These are the steps I took to analyse the Home ranges of past and present white-backed vultures and compare them against migratory wildebeest to answer my research questions of "Following the Feast"

This HTML shows the steps I took and the methods implemented to clean a set of GPS data comprising 19 vultures (Peregrine fund) and 186 wildebeest individuals (UofG).
