Network: BGP vs RIR IPv4 assignments

I have compared the values obtained from each registry against the prefixes announced in BGP (BGP potaroo IPv4 stats) and the results are presented on the chart. As far as the biggest registry is concerned (ARIN) the number of "active" prefixes (broadcasted in BGP) is significantly lower (at level of 60%) comparing to the number of assigned prefixes. Utlization rate of the other rirs is on a quite high level (for the smallest ones there are one or two prerfixes not announced in BGP). In the article I enclose the chart and the table presenting the values.
Registry BGP announced Allocated Percentage
Afrinic 1 2 50%
Apnic 34 43 79%
Arin 59 97 60%
Arin 59 97 60%
Lacnic 5 7 71%
Ripencc 32 40 80%
