About & Methods

In 2016 the Technology Alliance conceived of an interactive site that would show how technology is transforming industries across the state of Washington. The TechAlliance contracted Community Attributes Inc. to help turn this vision into a reality. Combining technology, data and stories, this site allows users to explore the many ways that technology influences, changes and is integral to the success of core industries in Washington.

  • STEM Employment: The employment in STEM occupations within a selected region or Washington state overall
  • Percent STEM Jobs: The share of total employment in STEM occupations within a selected region or Washington state overall.
  • Total Employment: Total employment within a selected region or Washington state overall.
  • STEM Graduates: The completions in a program matching to a STEM occupation from institutions located within a selected region or Washington state overall.
  • Top STEM Occupations: The top five STEM occupations within a selected region and the total number employed within that occupation and region.
  • Top STEM Industries: The top five industries within a selected region based on the share of STEM employment within that industry.
Data & Methods

The following are themes and methods used throughout the analysis presented on this site.


STEM is an acronym for Science, Technology, Engineering and Mathematics. This term is used throughout this site to demonstrate the proliferation of technology reliant occupations throughout Washington’s jobs and industries. Data and analysis here uses the definition of STEM provided by the SOC (Standard Occupational Code) Policy Committee Recommendation to OMB Attachment C. Data presented by region in the Washington map include employment in all STEM occupations listed in the OMB attachment above, across all industries.

STEM Employment

Crosswalks between NAICS and SOC codes help define estimates of STEM employment by region and/or industry. Industry-based county employment data is matched with the crosswalk of NAICS to SOC codes in order to estimate occupation-based employment by region. These estimates are then matched to the SOC codes defined as STEM by the SOC Policy Committee Recommendation to OMB. STEM employment by region covers employment across all industries.

STEM Graduates

Graduate data only measures the number of individuals that complete programs at postsecondary institution by CIP code, or Classification Instructional Program codes. The number of graduates matching an occupation are determined by using the NCES Program to Occupation crosswalk. Once the number of graduates matching to each occupation are estimated by region, these estimates are matched to STEM occupations to determine the number of STEM graduates by region. STEM graduates by region and statewide are the cumulative graduates from institutions within each region or statewide between 2005 and 2015.

Tech Employment

All references to Tech employment are estimated using the same methods as outlined under STEM Employment. However, the occupations included in the definition of Tech are a subset of STEM. The SOC codes included in the definition of Tech follow the Core ICT Occupations as outlined on page 7 of the Washington Technology Industry Association’s Information & Communication Technology Economic & Fiscal Impact Study.


The data for employment is defined by the four-digit North American Industry Classification System (NAICS).

Top industries by region presented in the Washington map include STEM employment in all STEM occupations within each specific industry. Specific NAICS codes for each top industry are:
