The realm of Perl development, a niche yet essential sector of the broader technology industry, is often overshadowed by flashier, newer languages. Yet, Perl, a high-level, general-purpose, interpreted, dynamic programming language, continues to hold its own, demonstrating a vitality that is fueled by a dedicated community of adept developers. The landscape of Perl developers is richly textured, marked by unique trends, insights, and key findings that are worthy of exploration.

Chronologically, Perl has been in the industry for over three decades. Having originated in the late 1980s, Perl has weathered numerous technological revolutions and continues to serve as a reliable language for a multitude of applications. Its longevity is a testament to its resiliency and adaptable nature. Perl’s inherent virtues such as text manipulation capabilities, comprehensive library modules, and the virtue of being a fully object-oriented language contribute to its staying power in the industry.

From a geographical perspective, Perl developers are spread across the globe, but there is a noticeable concentration in tech-hotspots such as the United States, Germany, the United Kingdom, Russia, and Japan. However, with the advent of remote working, the physical location of Perl developers is becoming increasingly irrelevant, transforming the industry into a truly global playing field.

The Perl developer community is an amalgamation of experienced professionals and enthusiastic newcomers. A survey conducted by Builtin reveals that a significant percentage of Perl developers have over a decade of experience under their belt, indicating the stable demand for Perl expertise. At the same time, there is a steady influx of new talent, attracted by the versatility of Perl and the wide range of applications it offers.

In terms of industry application, Perl is leveraged across a multitude of sectors, including web development, network programming, system administration, and bioinformatics, to name a few. Perl's ability to handle encrypted web data and its knack for text manipulation make it particularly suitable for these sectors. For instance, in bioinformatics, Perl is often used to handle and analyze massive amounts of genome data, thanks to its powerful text processing capabilities.

Looking through the lens of economic theory, there is a supply-demand equilibrium in the Perl developer market. On one hand, the supply of Perl developers, while not as massive as for languages like Python or JavaScript, is steady. On the other hand, the demand for Perl developers is stable, primarily driven by the industries that have grown dependent on Perl for their business-critical operations. This equilibrium has led to competitive remuneration for Perl developers, on par with, if not exceeding, those for other languages.

The Perl developer industry isn't without challenges, though. The primary obstacle is likely Perl's perception problem. Often labeled as an 'obsolete' or 'outdated' language, Perl does face a struggle in attracting new developers, especially in the face of competition from more modern languages. However, by parading its proven track record and the breadth of applications it can handle, Perl can continue to hold its ground.

In conclusion, the Perl developer industry is a dynamic ecosystem characterized by its stability, dedicated community, wide-ranging applications, and economic stability. Though faced with challenges, Perl has proven its mettle over the years and continues to be a potent force in the tech industry. This report on the Perl developer industry is an attempt to unveil the often-underestimated strength of this language and the impressive resilience of its developer community.
