This document discusses different models for estimating shelter requirements after earthquakes: SYNER-G, HAZUS-MH, ERGO-EQ, MCEER, InaSAFE, and RiskScape. It provides an overview of the conceptual frameworks and parameters considered in each model's calculations of displaced populations and shelter needs. These parameters include building damage, age, income, ethnicity, and others. The document also compares the outputs produced by each model, such as estimates of population displacement by geographic area or dwelling units. Future developments proposed include tailoring models to specific contexts and incorporating additional social and cultural factors.

Future Developments
• Adaptable models tailored to the specific context
and optional variables that will be able to fine
tune the social components of the estimate.
• Identification and calibration of other relevant
social and cultural location-specific parameters.
• Inclusion of this type of variables already in the
estimation of displaced people (e.g. SYNER-G,
MCEER and ERGO-EQ).
• Reduction of the uncertainty related to building
damage analysis outputs by using actual building
damage observation (for example, by inferring it
from building tagging system).
