Kenai
Peninsula Borough (KPB) staff develops quarterly reports containing economic
data from throughout the area for use by businesses, agencies, and other
entities to make planning and management decisions. The
publication is divided into eight sections: Kenai Peninsula Borough, Homer,
Kenai, Seldovia, Seward, Soldotna, KPB Unincorporated, and a Local Officials
Directory. To
provide unity within the document, certain conventions are applied: ·
Information sources for each section are listed in the index. ·
General information applicable to all sections is provided in the Kenai
Peninsula Borough section. ·
Percentages of parts may not total 100%, due to rounding. Information
presented will assist in decision-making by providing economic and demographic
information in graphic, table and text form.
Local and state government officials; local, state and federal
agencies; businesses within the borough and elsewhere; and private citizens
use data contained in the publication. Data
is received from various sources and is subject to change as updates,
revisions and corrections are received. The
KPB makes no claims to accuracy or completeness of information provided.
Only summary information is published.
For further detail, contact Jeanne Camp, Economic Analyst, KPB
Community and Economic Development Division, 907-714-2336, or the data source

Frequent
questions regarding differences between KPB the Community Economic Development
Division (CEDD) and the Economic Development District (EDD) suggest the need for
an explanation. The table below
defines the differences.
What is a “Moving Average Trendline?” Charts
in the KPB economic reports frequently include “moving average trendlines.”
After individuals read the documents, comments make their way back to the
office. One comment that has been
heard several times addresses these trendlines, noting that they are not labeled
correctly. They are.
A description of “trendline” is in order. The
purpose of a trendline is to demonstrate the average of data groupings and how
that average relates to averages of similar groupings within the chart. Imagine
that a bar chart illustrates twelve quarters of data and the subtitle states
“With Four Quarter Moving Average Trendline.”
The trendline begins at the fourth entry in the series and marks the
point representing the average of the first through the fourth numbers in
the series, in this case a 1st, 2nd, 3rd
and 4th quarter value, one year.
The trendline continues to the right in the chart.
As the trendline reaches the next entry in the series, the line will
move to the point on the scale representing the average of the second
through the fifth entries in the series – still four quarters of data;
but, this time those values would be the 2nd, 3rd and
4th quarter of the first year plus the 1st quarter of
the second year. The
process continues through the chart. As
the line moves through the chart, it drops the entry marking the beginning
of the previous trend point average, adds the entry just ahead of the
previous set of four and indicates the average of the new set of four
numbers in the series. The
resulting “smoothing” effect allows the reader to more easily see change
from one year to the next. |
