Incidents and Mobilisations Analysis
Variance Analysis
Introduction
58. The tables and variance charts in this section provide a summary of the measure of
incident activity for each station ground, to a measure of either population numbers,
household numbers, other buildings or road network. This gives an overview of incident
areas where the activity for each incident category is over, under or averagely represented
within the station ground.
59. Population and household numbers are obtained from the Mosaic 2009 dataset. Other
Buildings numbers are obtained from KFRS Technical Fire Safety CFRMIS database,
FSEC (Valuation Office records), focus group updates (local data collection), KCC data
(care home records) and Mosaic 2009 datasets.
60. Station incidents indicate the number of incidents of that type which were recorded on the
station ground between 01/01/2005 to 31/12/2009.
61. KFRS Incidents indicate the number of incidents for that category recorded for the whole
of KFRS.
62. % of Incidents is a percentage representation of the number of incidents on the station
ground to the whole of incidents within KFRS between 01/01/2005 to 31/12/2009.
63. Measure is the measurement unit used to determine the variance rate.
64. Station Figure is the number of measure units within the station ground. For example
where the measure is Population, this indicates the number of persons within the station
ground. Where the measure is Households this indicates the number of households within
the station ground. Where the measure is Other Buildings, this indicates the numbers of
buildings that are not classed as domestic single property or flats under 3 storey buildings
(see Annex 2), by FSEC within the station ground. Where the measure is Road Network,
this indicates the length of road network (Motorways, A Road Dual Carriageways, A Road
Single Carriageways, B Road Dual Carriageways, B Road Single Carriageways and C
Road Single Carriageways), within the station ground as recorded within FSEC.
65. The length of road network is a representation of route length and not carriageway length.
For example, for a dual carriage way running from A to B, the route length would be the
distance of routes A to B and B to A.
66. KFRS Figure is the number of measure units with the whole KFRS area.
67. % Measure is a percentage representation of the number of measure units on the station
ground to the whole of KFRS.
68. Variance is the ratio of the % of Incidents to the % of Measure. It indicates an over, under
or average representation within the station ground and is illustrated in the chart following.
