Consistency over time

At the industrial detail we estimate, industry profits (proprietor income and other property income) can swing significantly over time as prices and demand change from sector to sector and state to state. We also have the reality of County Business Patterns data which we use to disclose non-disclosed BLS Covered employment and wages data being inconsistent with each other which can drastically effect the non-disclosure estimates which in turn affects the distribution of 2-digit state GSP estimates to the counties and the more detailed IMPLAN sectors. As far as sectoral changes, we do provide a conversion bridge under downloads>implan supplemental files which you can apply to your older data to convert and at least make more consistent with the current sectoring. Our emphasis is on quality impact analysis data rather than time series data. When we change data reduction techniques or the government revises previous years' data we do not go back and redo the older IMPLAN data sets. The Es202 (covered employment and wages data - with our estimates for non-disclosed data) is our only true time series data.
