Disadvantages of the ACS Estimates
The ACS reports only what people fill out on their survey forms.
The estimates are limited by how many surveys the Census Bureau has collected.
(Sometimes ACS numbers are no d--- good.)
For small areas the ACS estimates cover a 3-year or a 5-year average time period, instead of just one year at a time.

Disadvantages of the ACS Estimates
You have to combine males and females to get a total.
You have to combine age groups.
You have to be concerned about recalculating the margins of error every time you combine anything.

SAHIE estimates are not based on a survey
They are based on a model. Inputs from several sources:
The population estimates program at the Census Bureau
Federal tax returns
County Business Patterns
Medicaid and Children’s Health Insurance Program (CHIP)
The Supplemental Nutrition Program (formerly food stamps)
The American Community Survey (SAHIE uses data from the ACS from all counties, even those where the sample size is so small that the data cannot be published in ACS tables.)

Advantages and Disadvantages of the SAHIE Estimates
The SAHIE estimates are more reliable because they use more data sources.
SAHIE gives comparable estimates for every county.
But there is a time lag. (2008 and 2009 became available in 2011.)
Because of methodological changes, the 2008 and 2009 estimates are not comparable to 2007 and previous estimates.
