description: Sterna antillarum browni) nested at 37 sites along the coast of California. This 7% decrease in breeding population size from 1994 brings to an end the trend since 1987 of continued growth of the population, and is likely attributable, at least in part, to the poor fledgling production experienced statewide in 1992. In addition to the drop in pair numbers, heavy predation pressure at many sites, an apparent shortage of food at two large sites, and a heavy storm in mid-June across the State, combined with a variety of human-related constraints on tern reproductive success, resulted in the lowest statewide fledgling-to-pair ratio recorded since fledgling production estimates were incorporated into monitoring protocol (1978). A minimum of approximately 963-1,174 fledglings was produced, 41% fewer than in 1994, resulting in a statewide fledgling per pair ratio of 0.37-0.45. As usual, successful and unsuccessful sites were distributed rather evenly throughout the State. Terns themselves were more unevenly distributed: 50% of the statewide population bred at only five sites (Venice Beach, Santa Margarita River/North Beach, Mission Bay/Mariner's Point and FAA Island, and Tijuana River/South); inclusion of an additional four sites (NAS Alameda, Bolsa Chica, Huntington Beach, and Delta Beach/North) accounted for 73% of all breeding pairs, and the inclusion of two more (Ormond Beach/Edison and Seal Beach) accounted for 81%. The fledglings produced at Santa Margarita River/North Beach, Mission Bay/Mariner's Point, and Delta Beach/North constituted 33% of the State total; the balance were distributed relatively evenly among sites.; abstract: Sterna antillarum browni) nested at 37 sites along the coast of California.

In 1996, 3330-3392 pairs of the endangered California least tern (Sterna antillarum browni) nested at 35 sites along the coast of California. This 29% increase in breeding population size over 1995 resumes the predominant pattern since 1987 of exponential growth of the statewide population. Fledgling-to-pair ratios at most sites increased relative to those in 1995, and terns nesting at several sites in 1996 were very successful. However, heavy predation at many San Diego County sites (including a majority of those with high pair numbers) and a local food shortage at Venice Beach compromised statewide fledgling production somewhat. Approximately 1981-2120 young terns fledged across the State, a record high and almost twice the number fledged in 1995; statewide F/P = 0.58-0.64. Most sites experienced increases over 1995 in the number of breeding pairs present, and several sites attracted more than 200 pairs. In 1996, 58% of the statewide population bred at only seven sites (NAS Alameda, Venice Beach, Huntington Beach, Santa Margarita River/North Beach, Mission Bay/FAA Island and Mariner's Point, Delta Beach/North), with the balance being distributed pretty evenly throughout the rest of the State. Almost half of the fledglings produced in the State came from only four sites; 45% of all potential new breeders produced this year fledged from NAS Alameda, Huntington Beach, Santa Margarita River/North Beach, and Delta Beach/North.

The dataset provides data on Municipal Unions (MUs) in Italy for the 1996-2015 period. Municipal Unions are forms of intermunicipal cooperation aimed at delivering municipal services and characterized by a high degree of formalization and institutionalization. The following 15 variables/indicators are taken into account: Year of establishment of the Municipal Union (Year); number of founding members (N founding members); number of members (N members 2015); number of member municipalities subject to compulsory cooperation by the Italian law (N C members); belonging (Y) or not (N) of all MU member municipalities to a unique Socio-sanitary District (Unique SSD); belonging (Y) or not (N) of all MU member municipalities to a unique Local Work System (Unique LWS); total inhabitants (Inh.N); inhabitants of the smallest member municipality (Inh.S); inhabitants of the largest member municipality (Inh.B); ratio smallest/largest population (Inh.R); average population (Inh.Av.); surface area (sq Km); average surface area (Av. Sur); Territorial Accessibility Index (TAI); Demographic Balance Index (DBI).
The dataset gives systematic information on Municipal Unions established in Italy from 1996 to 2015. Data relate to 2015, unless differently specified. A total number of 462 Municipal Unions is taken into account, that is all those present in the country at the year of data collection.
