Populations are counted and estimated in various ways. The most comprehensive population count available in Australia is derived from the Census of Population and Housing conducted by the Australian Bureau of Statistics every five years. However the Census count is NOT the official population of the City of Greater Shepparton. To provide a more accurate population figure which is updated more frequently than every five years, the Australian Bureau of Statistics also produces "Estimated Resident Population" (ERP) numbers for the City of Greater Shepparton. See data notes for a detailed explanation of different population types, how they are calculated and when to use each one.

  • Dry Seasonal Conditions in Rural Victoria
    Department of Primary Industries Dry Seasonal Conditions in Rural Victoria Report: 51 September 22, 2005 Environmental Indicators Rainfall August rainfall totals were close to normal. Over winter as a whole, rainfall was somewhat above normal in the North East and in East Gippsland, somewhat below normal in Central Victoria and in West Gippsland, and near to normal elsewhere. August had a warm spell at the end of the month following the widespread snow on the 10th. Overall daytime temperatures were 1°C above average and nightime temperatures were about average. For the 6-month period from March to August, serious to severe rainfall deficiencies extend from the far southeast of South Australia across southwest and south-central Victoria to west Gippsland. The deficiencies over southern Victoria are not as extensive or intense as they were at the end of July. The most significant rainfall in September occurred through the second week and varied from 0-5 mm in the north west to over 100 mm in pockets of the North East (Figure 1). The seasonal rainfall outlook for October to December indicates an increased likelihood of below median falls over parts of southern Victoria for the December quarter. Chances of above median rainfall are between 30 and 40% in a band extending from the far southeast of South Australia to West Gippsland. This includes most of the areas that have suffered severe short-term rainfall deficiencies since the start of autumn, and a general downturn in rainfall since the mid 1990s. The chances of a wetter than average season are between 40 and 50% over the rest of the State.

  • North Central Victorian Climate: Past, Present and Future
    North CENTRAL Victorian Climate: PAST, PRESENT AND FUTURE RO G ER N. JONES Centre for Strategic Economic Studies, Victoria University, PO Box 14428, Melbourne, Victoria 8001. Email: [email protected] JONES , R.N., 2010. North central Victorian climate: past, present and future. Proceedings of the Royal Soci- ety of Victoria 122(2): 147-160. ISSN 0035-9211. North central Victoria has experienced significant natural climate change over the past 20 000 years. At the height of the last ice age, the region was colder by 5°C or more with uplands and slopes under sub- alpine vegetation. Modern vegetation patterns were not established until the early Holocene. The first half of the Holocene was wetter than today, while the second half was affected by a less stable climate influ- enced by a strengthening El Niño–Southern Oscillation. Climate immediately prior to European occupation may have been wetter than during the historical period. Thus the pre-European climate and land surface influences on regional water balance may have been different to that which is generally assumed. Climate during the historical period was statistically homogenous, but with drier and wetter periods. Modest warm- ing began in the mid 20th century, by about 0.4°C per century from 1950 to 1996. From 1997, maximum temperature has undergone a significant upward step change (p<0.01) of 0.9°C. Rainfall has decreased by 19%, with May–October rainfall undergoing a significant (p=0.05) downward step change from 2000. Maximum temperature is now non-stationary with respect to rainfall and is experiencing an upward trend consistent with climate model projections.
