GenCode has a wonderful breakdown of the number of coding/non-coding genes and transcripts here...

http://www.gencodegenes.org/stats.html

Does a similar breakdown exist for RefSeq anywhere?  Thanks!
If you take a look at this [hg19/GRCh37 GFF file from NCBI][1] here is what is in there:

       1 RNase_P_RNA
       2 SRP_RNA
       4 Y_RNA
      22 antisense_RNA
    19086 cDNA_match
    618452 exon
    30661 gene
    6405 lnc_RNA
    49861 mRNA
