Question: What is the population of the geographical region with a relatively high population density at its core and close economic ties throught the area that is in Lebanon Country, Pennsylvania?

<P0-S0> This is a list of the cities worldwide that have the highest population density. <P0-S1>  The population, population density and land area for the cities listed are based on the entire city proper, the defined boundary or border of a city or the city limits of the city. <P0-S2>  The population density of the cities listed is based on the average number of people living per square mile or per square kilometre. <P0-S3>  This list does not refer to the population, population density or land area of the greater metropolitan area or urban area, nor particular districts in any of the cities listed. <SEP> <P1-S0> The forest dormouse ("Dryomys nitedula") is a species of rodent in the family Gliridae found in eastern Europe, the Balkans and parts of western Central Asia. <P1-S1>  It is categorized as being of least concern in the "IUCN List of Threatened Species" due to its wide range and stable population trend. <P1-S2>  Forest dormice have a diploid count (2n) of 48 chromosomes. <P1-S3>  Even though this species lives in a variety of geographic locations, its greatest population density is in the forests of central Moldova, in Transcaucasia, in the mountains of Central Asia. <P1-S4>  In most other locations, population density of this species is rather low. <P1-S5>  Population density is dependent on many factors. <P1-S6>  But the main features that this species depends on for choosing a location are the presence of the appropriate food sources as well as good foliage that can be used for a habitat. <P1-S7>  The reason why the forests in central Moldova have the highest population density is they provide the largest diversity of food sources which are available throughout the year. <P1-S8>  This location also provides the best type of foliage for the forest dormice to build their nests as well as swing from branches. <P1-S9>  The combination of both of these aspects allows for this species to have its highest needs met. <P1-S10>  Therefore, during mating season they produce offspring who also stay in the same general area when they mature. <P1-S11>  It makes sense not to move from an area if it is providing for your most basic needs. <SEP> <P2-S0> Palmyra is a borough in Lebanon County, Pennsylvania, United States. <P2-S1>  It is part of the Lebanon, Pennsylvania Metropolitan statistical area. <P2-S2>  The population was 7,096 at the 2000 census. <SEP> <P3-S0> In the United States, a metropolitan statistical area (MSA) is a geographical region with a relatively high population density at its core and close economic ties throughout the area. <P3-S1>  Such regions are neither legally incorporated as a city or town would be, nor are they legal administrative divisions like counties or separate entities such as states. <P3-S2>  As such, the precise definition of any given metropolitan area can vary with the source. <P3-S3>  A typical metropolitan area is centered on a single large city that wields substantial influence over the region (e.g., Chicago or Atlanta). <P3-S4>  However, some metropolitan areas contain more than one large city with no single municipality holding a substantially dominant position (e.g., Dallas–Fort Worth metroplex, Norfolk-Virginia Beach (Hampton Roads), Riverside–San Bernardino (Inland Empire) or Minneapolis–Saint Paul).
