EA published new apartment data today—historical and forecast for Q1 2018.
This release features revisions to our historical time series, occasioned by growth in the dataset (including the addition of four markets: Colorado Springs, Dayton, Lexington and Omaha). As our data providers continue to expand their metro sample sizes and their overall geographic coverage, we have revised our methodology for aggregating property-level data to the market level. This gives us greater flexibility in incorporating the new data. With the Axiometrics, Inc. and RealPage platforms in the process of merging, this flexibility will remain important as we enhance our databases with new properties and geographies.
So what do the results look like? In general, the trends that have been observable in recent quarters' data remain present in the revisions, and most market histories were affected to just a small degree. A notable exception is the large upward revision to New York City’s rent growth. Because of New York’s relative size, we also see a material revision to the Sum of Markets headline rent growth series.
As always, we are available to answer any questions you may have. These changes are only meant to bring our clients the best and most accurate data possible.
 The city's recent trend toward softening rent performance also remains evident.
