Hi everyone,

Here are some OSMPH data stats as of April 1, 2012 (last Geofabrik
extract before the server downtime/migration) compared to the start of
2011 and the start of 2012:

Stats as of 2011-01-03*:
OSM XML file size : 324 MB
# Nodes: 1,528,760
# Ways: 127,544
# Relations: 645
Total length of highways**: 59,969 Km

Stats as of 2012-01-02:
OSM XML file size : 550 MB    (70% increase)
# Nodes: 2,779,792    (82% increase)
# Ways: 284,262    (123% increase)
# Relations: 1,776    (175% increase)
Total length of highways**: 86,794 Km   (45% increase)

Stats as of 2012-04-01 (increase compared to start of 2012):
OSM XML file size : 634 MB    (15% increase)
# Nodes: 3,222,586    (16% increase)
# Ways: 323,359    (14% increase)
# Relations: 1,833    (3% increase)
Total length of highways**: 99,934 Km   (15% increase)


If we extrapolate the 2012 growth to the end of 2012 we would have the
following projected stats:
OSM XML file size : 880 MB
# Nodes: 4,560,000
# Ways: 440,000
# Relations: 2,000
Total length of highways: 139,000 Km

* This is based on maning's stats.
** I think maning and I use different metrics for calculating the
length of highways and that is why my figure for April 2012 is less
than the 100,000 Km that maning posted recently. In addition, we
currently don't account for dual-carriageway highways. So take the
kilometer lengths as a rough metric.
