2018 Supplemental Poverty Measure (SPM) Research File

Component ID: #ti1677528395

Due to an error in our tax model, tax units with an Adjusted Gross Income (AGI) below $12,000 were inadvertently not run through the Additional Child Tax Credit (ACTC) portion of the tax model. As a result, 2,435 tax units did not receive this refundable credit, which changed the Supplemental Poverty Measure (SPM) poverty status of about 600 individuals (or 0.3% of the weighted population). This error changed our top-level SPM estimate from 13.1% for 2018 to 12.8%. Using either set of estimates, the change between 2017 and 2018 was not significant overall or for any of the major age categories. All SPM estimates have been revised accordingly.
