 ==== Questions and Available Data ====
+  * Our digital job register data goes back to 2003.
+  * Our digital membership data goes back at least 10 years.
+    * Demographic information is self-reported and not broadly consistent with federal standards of classification.
+    * Our membership data will have the unclear bias of "people who choose to be AAS members."
+    * It is not obvious how this would bias the information.
+      * Possible examples:
+        * Are we undersampling small institutions?
+        * Are some other institutions over or under-represented based on local department culture?
+        * Are astronomers from certain types of institutions more likely to be AAS members?
+    * In addition, the overlaps between our membership and the proposing-and-funded or proposing-and-not-funded cohorts are unclear.
+  * We think we could provide a secondary estimate of the field demographics to compare to the agencies' datasets, but as a primary source, our data would introduce unclear biases.
+  * Draft v2 of our proposed AAS member survey on grant proposal success rates available {{:aaac:aas_prop_pressure_survey.v2.docx|here}}
