C., 1992.Some Explanations for <strong>the</strong> Emergenceof EnclavesIn earlier works, <strong>the</strong> authors (García <strong>and</strong> González,1995; García, 1997) employed <strong>the</strong> agricultural restructur<strong>in</strong>ghypo<strong>the</strong>sis, as used by Palerm (1991) <strong>and</strong> Krissman(1995), to expla<strong>in</strong> <strong>the</strong> emergence <strong>and</strong> <strong>the</strong> growth of <strong>Mexican</strong>enclaves <strong>in</strong> Sou<strong>the</strong>rn Chester County. 13 Basically,<strong>the</strong> hypo<strong>the</strong>sis postulates that <strong>the</strong> restructur<strong>in</strong>g of agriculturalenterprises <strong>and</strong> <strong>the</strong> <strong>in</strong>tensification of crop productionaugment <strong>the</strong> number of farmworkers needed over agiven year, many of whom settle down with <strong>the</strong>ir families,alter<strong>in</strong>g <strong>the</strong> ethnic <strong>and</strong> demographic composition oflocal communities. Additionally, <strong>the</strong> authors argued that<strong>the</strong> SAW Program, a government program designed tocontrol <strong>the</strong> flow of labor <strong>in</strong>to <strong>the</strong> country, played a role <strong>in</strong><strong>the</strong> emergence <strong>and</strong> growth of <strong>the</strong> <strong>Mexican</strong> enclaves (García<strong>and</strong> González, 1995; García, 1997). SAW, like <strong>the</strong>Bracero Program, allowed <strong>Mexican</strong> families to immigrate<strong>in</strong>to <strong>and</strong> settle <strong>in</strong> <strong>the</strong> region. 14Subsequently, however, <strong>the</strong> authors have concludedthat <strong>the</strong> agricultural restructur<strong>in</strong>g hypo<strong>the</strong>sis was onesided,<strong>and</strong> as such, does not expla<strong>in</strong> why transnationalmigrants only jo<strong>in</strong> <strong>the</strong>ir immigrant compatriots on a seasonalbasis. Transnational migration, as researchers of<strong>the</strong> <strong>Mexican</strong> peasantry (González, 1992; Palerm <strong>and</strong>Uriquiola, 1993; Palerm, 1997) have discovered, is a b<strong>in</strong>ationalphenomenon <strong>and</strong> any explanation of <strong>the</strong> movementof workers across <strong>the</strong> border requires thatcontribut<strong>in</strong>g factors <strong>in</strong> both countries to be explored.They have shown that <strong>the</strong> two agricultural systems, one<strong>in</strong> <strong>the</strong> U.S. <strong>and</strong> <strong>the</strong> o<strong>the</strong>r <strong>in</strong> Mexico, are <strong>in</strong>tr<strong>in</strong>sicallyl<strong>in</strong>ked <strong>and</strong> highly dependent on each o<strong>the</strong>r. For example,<strong>the</strong> vegetable <strong>and</strong> fruit <strong>in</strong>dustries <strong>in</strong> California <strong>and</strong> o<strong>the</strong>rstates provide <strong>the</strong> peasantry with an <strong>in</strong>come essential tocont<strong>in</strong>ue subsistence farm<strong>in</strong>g; <strong>in</strong> turn <strong>the</strong> peasantry provides<strong>the</strong>se <strong>in</strong>dustries with cheap labor that allows <strong>the</strong>mto survive <strong>and</strong> rema<strong>in</strong> competitive <strong>in</strong> <strong>the</strong> global economy(González, 1992; Palerm <strong>and</strong> Uriquiola, 1993).6Transnational migration is an economic practice thatallows campes<strong>in</strong>os to cont<strong>in</strong>ue to supplement subsistencefarm<strong>in</strong>g. Subsistence agriculture is a risky farm<strong>in</strong>gendeavor, <strong>and</strong> it alone does not meet <strong>the</strong> basic food needsof <strong>the</strong> producers <strong>and</strong> <strong>the</strong>ir families. Despite <strong>the</strong>se shortcom<strong>in</strong>gs,peasants <strong>in</strong> Guanajuato <strong>and</strong> o<strong>the</strong>r states of <strong>the</strong><strong>Mexican</strong> republic do not easily ab<strong>and</strong>on agriculture forpermanent employment elsewhere (González, 1992;1994; 1995; Cebada Contreras, 1993; 1994; DelgadoWise <strong>and</strong> Moctezuma Longoria, 1993). However, somepeasants, those tired of endur<strong>in</strong>g <strong>the</strong> uncerta<strong>in</strong>ties of production<strong>and</strong> those unable to obta<strong>in</strong> l<strong>and</strong> of <strong>the</strong>ir own, mayleave when o<strong>the</strong>r economic opportunities present <strong>the</strong>mselves.Instead of ab<strong>and</strong>on<strong>in</strong>g <strong>the</strong> l<strong>and</strong>, <strong>the</strong> majority of<strong>the</strong>m practice o<strong>the</strong>r economic activities that supplement<strong>the</strong>ir crop production, particularly migration (González,1992; Palerm <strong>and</strong> Urquiola, 1993). An outsider, someonenot familiar with <strong>the</strong> culture, would see <strong>the</strong> peasantry’sreluctance to ab<strong>and</strong>on <strong>the</strong> l<strong>and</strong> as irrational <strong>and</strong> a loss ofeconomic opportunity that may be found elsewhere. Acloser look reveals that subsistence farm<strong>in</strong>g is more thanan economic activity. It’s a traditional way of life <strong>in</strong>many areas of Mexico.Conclusion<strong>Mexican</strong> immigration to <strong>the</strong> <strong>United</strong> <strong>States</strong>, especiallyfrom Guanajuato, has occurred s<strong>in</strong>ce <strong>the</strong> turn of <strong>the</strong> century.Over <strong>the</strong> decades, as current settlement concentrations<strong>in</strong>dicate, guanajuatenses have settled <strong>in</strong> <strong>the</strong> U.S.southwest ma<strong>in</strong>ly <strong>in</strong> metropolitan areas, but a significantnumber were also homesteaders outside of this region.<strong>Guanajuatense</strong>s settled <strong>in</strong> non-metropolitan areas <strong>in</strong> <strong>the</strong>Northwest <strong>and</strong> Midwest, but until <strong>the</strong> 1960’s, when <strong>the</strong>Bracero Program was term<strong>in</strong>ated, <strong>the</strong>ir numbers were torema<strong>in</strong> small. The majority were migrants, <strong>and</strong> as such,only worked <strong>in</strong> <strong>the</strong> <strong>United</strong> <strong>States</strong> temporarily while liv<strong>in</strong>g<strong>in</strong> Mexico permanently.Start<strong>in</strong>g <strong>in</strong> <strong>the</strong> 1980’s, earlier <strong>in</strong> some <strong>in</strong>stances, gua -najuatenses <strong>and</strong> o<strong>the</strong>r <strong>Mexican</strong> immigrants began to settle<strong>and</strong> change <strong>the</strong> ethnic <strong>and</strong> demographic characteristicsof many towns <strong>and</strong> cities <strong>in</strong> <strong>and</strong> around non-metropolitanareas of <strong>the</strong> country, as a result of <strong>the</strong> restructur<strong>in</strong>g <strong>and</strong><strong>in</strong>tensification of U.S. food production <strong>and</strong> process<strong>in</strong>g.These <strong>Mexican</strong> residents <strong>and</strong> <strong>the</strong>ir children establishedenclaves, where immigrants <strong>and</strong> migrants alike, sought<strong>and</strong> cont<strong>in</strong>ue to seek solace, hous<strong>in</strong>g, <strong>and</strong> employment.Kennett Square <strong>and</strong> Toughkenomon are examples of suchenclaves. Twenty years ago, <strong>Mexican</strong>s were not immigrat<strong>in</strong>g<strong>in</strong>to Sou<strong>the</strong>rn Chester County; <strong>the</strong>y were onlymigrat<strong>in</strong>g. Today, many of <strong>the</strong>se migrants are settl<strong>in</strong>gdown with <strong>the</strong>ir families <strong>and</strong> establish<strong>in</strong>g <strong>the</strong>ir own communities.
The <strong>Mexican</strong> newcomers <strong>in</strong> Kennett Square,Toughkenomon, <strong>and</strong> numerous o<strong>the</strong>r enclaves across <strong>the</strong><strong>United</strong> <strong>States</strong> harvest a variety of crops <strong>and</strong> hold jobs <strong>in</strong>food-process<strong>in</strong>g plants. Employment <strong>in</strong> this l<strong>in</strong>e of workis sporadic <strong>and</strong> seasonal, <strong>and</strong> provides wages at or near <strong>the</strong>poverty level. Despite <strong>the</strong>se serious obstacles to <strong>the</strong>irlivelihood, <strong>Mexican</strong> immigrants have what it takes toovercome <strong>the</strong>m. They have a strong work ethic, aspire toimprove <strong>the</strong>ir plight <strong>and</strong> better <strong>the</strong> opportunities of <strong>the</strong>irchildren, <strong>and</strong> have a strong will to build stable families<strong>and</strong> communities. If <strong>in</strong>corporated <strong>in</strong>to <strong>the</strong>ir communitiesas full <strong>and</strong> legitimate members, <strong>the</strong>se new immigrants willhelp rebuild communities <strong>and</strong> local economies. As is happen<strong>in</strong>g<strong>in</strong> Kennett Square <strong>and</strong> Toughkenomon, <strong>the</strong>y willopen small bus<strong>in</strong>esses with <strong>the</strong>ir sav<strong>in</strong>gs; pay bus<strong>in</strong>ess,sale, <strong>and</strong> o<strong>the</strong>r taxes contribut<strong>in</strong>g to municipal revenues;shop <strong>in</strong> local stores keep<strong>in</strong>g bus<strong>in</strong>esses afloat <strong>and</strong> open;<strong>and</strong> rebuild <strong>the</strong>ir homes <strong>and</strong>, revitaliz<strong>in</strong>g neighborhoods.ReferencesAlmanza B., Miguel Angel <strong>and</strong> Lucero Circe LopezRiofrio. 1997. “De aquí y de allá: Reflexiones generalesde fenómeno migratorio <strong>in</strong>ternacional y losjóvenes.” Gente: Revista del Consejo Estatal dePoblación Guanajuato, VII (2): 36-41.Argüello Zepeda, F. 1993.
