| Approximately 25% of patients with acute glomerulonephritis present with nephritic syndrome.<ref>{{cite book | last = Chang |first = A | authorlink = | coauthors = Pradeep VK, Alexander JJ | title = Glomerulonephritis, Membranopoliferative In: Lang F, ed.

While some studies report a decrease in the incidence due to improved healthcare and socioeconomic status, others report an increase in the reported incidence due to increased number of biopsies.<ref name="pmid21068142">{{cite journal| author=McGrogan A, Franssen CF, de Vries CS| title=The incidence of primary glomerulonephritis worldwide: a systematic review of the literature. | journal=Nephrol Dial Transplant | year= 2011 | volume= 26 | issue= 2 | pages= 414-30 | pmid=21068142 | doi=10.1093/ndt/gfq665 | pmc= | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=21068142 }} </ref> Additionally, the true incidence is difficult to predict because the disease might present subclinically.
