MRCOG’s DASZ datasets include current and forecast data that pertain to population, housing, employment, and school enrollment by Data Analysis Subzone (DASZ). DASZs are small units of geography that are compatible with MRCOG's transportation model. The datasets are created by MRCOG to project future travel demand in the region. However, their use extends beyond travel demand forecasting to land use planning, economic development and so on.

The value of DASZ data is that they equip planners and the public with small area data that is more current than what the 2000 Census provides. Our 2004 dataset shows us where recent growth in the region has occurred, and our 2030 dataset shows us where future growth is expected. DASZs are generally bounded by major roads and other physical features, and subdivisions of Census Tracts.

The  Data Dictionary provides definitions of the variables that may be included in each datase.

The 2030 DASZ Forecast dataset was created for the 2030 Metropolitan Transportation Plan (MTP). The creation of the MTP is a participatory process with member governments and the Department of Transportation, and results in a long range plan that outlines how federal transportation dollars will be spent. This dataset helps planners anticipate future demand and thus prioritize future transportation projects. The forecast overview and methodology is provided in  2030 Socioeconomic Forecasts by DASZ 775.00 Kb for the Mid-Region of New Mexico.

The 2004 DASZ dataset was created as an update to the 2000 dataset using building permits for new construction, school enrollment data, tax assessor data, aerial photography, and employer addresses as provided by the New Mexico Department of Workforce Solutions.

The 2000 DASZ dataset contains data from the 2000 Census, the New Mexico Department of Workforce Solutions, and public school districts. The data have been adjusted into DASZ geography by MRCOG. Because 2000 was a Decennial Census year, MRCOG has added a number of variables from the 2000 Census outside of what is required by the travel model, which allows this data set to be used for a wide variety of purposes.

2025 DASZ Forecast

The following forecasts are now considered obsolete and should only be used for historical purposes.  They were developed in 2003 for the 2025 MTP, and therefore are superseded by the 2030 forecast.
