Survivorship and Population Structure—Cemetery Demography (ESA EcoEd Digital Library)

This module provides access to data uploaded by users themselves via the My Data section of the site, and from seven cemeteries in the Wyoming Valley of northeastern Pennsylvania, collected by students in Wilkes University's BIO 344 Ecology course:

1989 - Hollenback Cemetery, Wilkes-Barre, Luzerne County, PA  (41° 15.510’ N; 075° 52.214’ W)
1993 – Forty Fort Cemetery, Forty-Fort,  Luzerne County, PA (41° 17.132’ N; 075° 52.302’ W)
1997 – St. Mary’s Cemetery, Hanover Township, Luzerne County, PA (41° 13.249’ N; 075° 55.149’ W)
1999 - Hanover Green Cemetery, Hanover Township, Luzerne County, PA (41° 13.017’ N; 075° 57.245’ W)
2004 – Pittston Cemetery, Pittston, Luzerne County, PA (41° 18.807’ N; 075° 47.572’ W)
2006 – Maple Hill Cemetery, Hanover Township, Luzerne County (41° 13.240’ N; 075° 54.950’ W)
2008 – Wyoming Cemetery, Wyoming, Luzerne County, PA  (41° 18.915’ N; 075° 50.078’ W)

The Survivorship Data component outputs data from one of the selected cemeteries, or from a user uploaded dataset (MyData1-5). You may learn more about uploading and using your own data here. Uploaded data must be no larger than 200KB, and conform to the Demography Data Format.

Demography Data Format

The Demography Data Format is is 5 columns of comma separated values, with these exact column names:

Name,Sex,Birth Year,Death Year,Age(years)

In each data row, sex should be specified with one character, and years in YYYY format. E.g.:

Ada J,M,1867,1910,43
All S,F,1838,1932,94

Data may be filtered by individuals' year of birth, year of death, age at death, and sex.

The Data Grouper actor is used to group ("bin") data by a selected Group By parameter, into bins of a specified size. For example, a user can bin data by age at death, into intervals of 5 years, and then feed this grouped ("binned") data into the Histogram component to see frequency of death by age intervals.

The Survivorship Calculator component outputs a summary Life Table, which may be viewed with the Data Viewer component. It also outputs each individual column of the life table, and these may be used to produce line charts (e.g. survivorship curves) using the Line Chart actors.
