Administrative divisions of Castadilla

The administrative divisions of Castadilla are the non-national levels of governance in Castadilla. As a federal state, the exact powers and responsibilities of each administrative level are specified as per the Constitution of Castadilla with the first-level divisions entitled to their own constitutions so long as it's not in violation of the nation's constitution. There are twenty first-level entities, consisting of sixteen states, three autonomous islands, and a federal district for the capital of Santa Maria. Despite the different designations, the autonomous islands and the federal district are equal to the states in both autonomy and function.

Both the national and state governments are structured in a similar manner. Each have a bicameral legislature consisting of a popularly-elected lower house and an indirectly-elected upper house, and a parliamentary-based system (though whether or not it's more dominant than the executive depends on the state). This is a far cry from the more centralised form of government that had existed from 1924 until 1984, of which the final remnant lies in the education system which remains highly centralised to this day.

All the states, autonomous islands, and federal district are further subdivided into provinces (states), counties (autonomous islands), and boroughs (federal district). These are then divided into hundreds of parishes (states), collectivities (autonomous islands), and districts (federal district); these serve as a collection of multiple collections of localities and were mostly around for administrative reasons for the provincial level. Beneath these are the cantons (states), grouped settlements (autonomous islands), and wards (federal district), with municipalities (states), settlements (autonomous islands), and neighbourhoods below even that. Overall, these second-, third-, fourth-, and fifth-level divisions each have their own authorities and responsibilities.

In the name of developing a better understanding of both the geography of the nation as well as its cultural heritage, maps have been made depicting the cultural areas of the nation as well as maps depicting the geographical divisions. The former is used by the Castadillaan Bureau of Statistics and Censuses to categorise the states based on a common geography while the latter has been used by cultural institutions to foster the awareness and preservation of the cultural heritage of the nation. Otherwise, neither of these two designations carry no authority nor responsibility in of themselves beyond serving as a reference point.

Cultural areas

Loaland	Portascolinia

Castadilla is divided into four cultural areas so as to provide a greater understanding of the nation's cultural diversity and its history. While they are not official government entities, they do serve as essential reference points for the cultural institutions of the nation.

The Delepasian Area is by far the largest of the cultural areas, encompassing 943,645.57 square kilometers (364,343.59 sq mi) across the states of Rosaria, Terregran, Rios Gemelos, Junu'urinia Ba'andasi-Navidadia, Bahia, Rio Solo, Lagocia, Homberia, and Auxana, the autonomous islands of Valio and New Isuria, and the Santa Maria District. In this cultural area, the Delepasians make up the vast majority of the population, many of whom are Catholic and almost all speak the Castadillaan vernacular of Pelaxian. Almost all of these states, except for Junu'urinia Ba'andasi-Navidadia, were a part of the Pelaxian Viceroyalty of Los Rumas.

The Tainean Area is the second-largest, encompassing 311,683.44 square kilometers (120,341.65 sq mi) across the states of Ibimini, Inaua, and Kauabimini. This, asides from Arona, constitute as the only two countries on Vallos where the Tainean people make up not only an absolute majority, but are also major strongholds of the Tainean culture and the Tainean language, specifically Reform Tainean. In Castadilla, Reform Tainean carries some Burgoignesc influences and innovations even as the Tainean Linguistic Academy takes the language through a process of re-Taineanisation.

The Loa Area is the third-largest, encompassing square kilometers 240,244.27 (92,758.83 sq mi) across the states of Junu'urinia Ba'andasi-Navidadia, Kalanatoa, and Na'aturie. This area was historically a part of the Loa Empire until its collapse in 1875. The Loa make up the vast majority of people in this area, and all of them practice a syncretic faith known as Marian Kapuhenasa, combining elements of Loa Kapuhenasa with Delepasian Catholicism. This cultural area also boasts having the highest amount of women in public office as well as in ecclesiastical posts, a result of the matriarchal culture of the Loa.

The Cartadanian Area is the smallest of the cultural areas, encompassing 39,453.60 square kilometers (15,233.12 sq mi) across the state of Portas Gemeas and the autonomous island of Trescolinia. Both the Cartadanian people and the Cartadanian language are dominant in this cultural area. The culture here has some Tainean influences, given its close proximity to the Tainean Area, as well as maritime overtones due to it being on a coastal area as well as its history with pirates.

These four areas are a backdrop for the extent of the major cultures which inhabit Castadilla. As shown, Junu'urinia Ba'andasi-Navidadia is the only state that's in two cultural areas, mostly owing to it having been the northeastern most part of the Loa Empire as well as the century-long rule of the Delepasians who settled and established Navidadia despite never having been a part of the Viceroyalty of Los Rumas.

Geographical divisions

The seven geographical regions of Castadilla.

LR (Loru)	LD (Lade)	TL (Tilo)
NR (Nuru)	TDL (Tridesu)	GDN (Gedeno)
NM (Noma)

The geographical divisions of Castadilla are designated and used by the Castadillaan Bureau of Statistics and Censuses for statistical purposes in data collection and analysis. These divisions are grouped based on a common geography regardless of culture, usually using a river or a mountain as boundaries with the idea being that those natural features have more often than not determined the demographics of a given area even to the present. There exists seven geographical divisions: Los Rumas (LR; Loru) (Rosaria, Bahia, New Isuria, Valio, and the Federal District), Lago Delepas (LD; Lade) (Lagocia, and Junu'urinia Ba'andasi-Navidadia), Tierra Loa (TL; Tilo) (Kalanatoa, and Na'aturie), New Rumas (NR; Neru) (Rio Solo, and Homberia), Trillizos del Sur (TDS; Tridesu) (Rios Gemelos, Auxana, and Terregran), Gemelos del Norte (GDN; Gedeno) (Ibimini, and Kauabimini), and Norte Maritimo (NM; Noma) (Inaua, Portas Gemeas, and Trescolinia). Other than statistics, the geographical divisions have no further authority nor any additional responsibilities.

The geographical divisions were first designated in 1998, following a fifteen-year-long commission to determine the exact boundaries for each of the geographical divisions. Various ideas included simply using the state boundaries, exclusively following any and all natural borders, and some have even proposed designating geographical divisions based on the four cardinal directions. Eventually, the CIPCDE decided to come up with a compromise: the boundaries of the geographical divisions will follow natural boundaries, but it will also follow state boundaries as needed, and certain divisions may be designated based on a commonality such as a lake (as with Lago Delepas) or historical significance (as with Los Rumas and Tierra Loa). The new geographical divisions were first used in the 2000 Castadillaan census, replacing the previous designation based on the nation's history (e.g. Delepasian-majority states were designated as a part of 'Delapasia proper'; Navidadia was designated 'New Delepasia'; the northern non-Delepasian states were designated 'New Semi-Civilised Territories') which faced criticism due to its arbitrary nature and how it never properly divided the territory into anything statistically meaningful.

Of the geographical divisions, Trillizos del Sur is the largest by area, encompassing 327,183.07 square kilometers (126,326.09 sq mi), with Tierra Loa being the smallest by area, encompassing 114,274.55 square kilometers (44,121.65 sq mi).

First-level divisions

Castadilla is divided into nineteen first-level divisions, those being sixteen states, three autonomous islands, and one federal district. Despite the distinct designations, there exists no difference in autonomy or authority between the states, autonomous islands, and federal district beyond land area.

According to the constitution, the twenty first-level divisions are 'semi-sovereign states' wherein they have the right and responsibility to oversee domestic affairs and matters pertaining to their territory all the while being under the legal oversight of the national government, thus meaning that one such division may not pass a law that violates a nation-wide law or the Castadillaan constitution. As such, they are not seen as fully sovereign states under international law but rather under the jurisdiction of Castadilla.

Each state has its own identification number for internal administrative purposes and to ensure that confusion is avoided with certain states that have similar-looking names. These numbers are chosen at random, with only the the sole letter being used to determine the period of time in which the state was admitted. For example, Rosaria has the identification number of E-A113, with A being used to denote the original 16 states of the nation. The Federal District is reserved and given the special letter Z to indicate its status as the federal district, and thus carries the identification number of E-Z478.

Second-level divisions

The highest tier of sub-national division for the nineteen first-level divisions are the provinces, the counties, and the boroughs, respectively the primary divisions of the states, the autonomous islands, and the federal district, all designated as "a collection of collectivities subordinate to their respective home regions" and as such any boundary changes to these sub-divisions are the responsibility of the legislators to their home regions. As Castadilla is committed to federalism, these sub-divisions are allocated devolved powers alongside their secondary purpose for state-wide statistics.

The main governing bodies of these sub-divisions are the deputy councils whose members are indirectly elected (i.e. appointed) by the councils of their subordinate regions (the third-level divisions). The deputy councils coordinate with and provide assistance to the lower levels in ensuring that the necessary services provided by the state are acceptable in the eyes of the national inspectors, people who conduct surprise thorough investigations in behalf of the national government to weed out regional corruption and areas in need of attention (such as underdeveloped villages or a lack of up-to-code infrastructure).
