g_cpc_current significantly smaller than g_cpc_at_issue
Hi,
I noticed that in the bulk donwload page, g_cpc_current has only 243k observations, whereas g_cpc_at_issue has 20 million and significantly larger in size. I remotely remember that these two datasets seem to be of similar size -- is there any error going on here? Thansk a lot.
Best,
Junxi
