	~~#REDIRECT~~ [[~~Nations~~#GDP]]		A [[nation]]'s GDP is a measure of its economic output. It is measured in US dollars. In the real-world [[scenarios]] of [[2003]], [[2022]], and [[2026]], the starting GDP figures for nations are taken from their real-world economic output, adjusted for purchasing power parity.

			The closely related statistic of GDP per capita (abbreviated [[GDPPC]]) is equal to the GDP divided by the {{TV\|pop}}.

			== Changing GDP ==
			In a nation with {{TV\|pop\|50 million}}, each completion of the {{TV\|economy}} increases the GDPPC by:
			* 3 (Base value), slightly increased by certain global [[technologies]].
			* +1.5 per {{icon\|oil}}Oil [[Region]]
			* +1.5 per {{icon\|resource region}}Mining Region.
			* +1.5 per {{icon\|core economic region\|bgcolor=DarkSlateGray}}Core Economic Region.
			* +0.5 per {{TV\|democracy}}.
			* +1 per {{TV\|education}}.
			In nations with smaller or larger {{TV\|pop}}, these changes are sped up or slowed down. See [[Population Scaling]] for more detail.

			This means that for maximum GDP growth, you want higher {{TV\|democracy}}, higher {{TV\|education}}, as well as as many {{icon\|core economic region\|bgcolor=DarkSlateGray}}economic, {{icon\|oil}}oil, and {{icon\|resource region}}mining regions as possible.

			GDP is negaively affected by [[Climate Change]], with a rate of annual decrease that is based on global pollution levels, national {{TV\|inequality}}, and [[region]] characteristics.

			GDP can also be affected by [[events]], and regional GDP can be affected by certain [[projects]] (in particular, the bridge/tunnel/etc. projects unlocked by [[Arrival International Development]]).

			== Monthly Investment Points ==
			GDP directly determines the number of {{TV\|IP}} a nation has to distribute to priorities. These represent the nation's economic surplus that can be distributed by factions with [[Control Points]] in the Priorities tab. The value is set by the nation's GDP and reduced by the number of [[Armies]] and [[Navies]] it fields and by high levels of {{TV\|unrest}}. The {{TV\|Broken Earth}} scenario uses different mechanics here, so the differences are summarized below:

			{\| class="wikitable"
			\|+ Monthly Investment Points
			\|-
			! Value !! Impact in {{TV\|2022}}/{{TV\|2026}}/{{TV\|2070}}/{{TV\|2003}} !! Impact in {{TV\|Broken Earth}}
			\|-
			\| Base IP \|\| (GDP in billions)<sup>0.35</sup> \|\| 0.62 * (GDP in billions)<sup>0.48</sup>
			\|-
			\| [[Army]] Maintenance (Home Region) \|\| {{TV\|IP\|0.5}} per army \|\| {{TV\|IP\|0.2}} per army
			\|-
			\| Army Maintenance (Away from Home) \|\| {{TV\|IP\|1.0}} per army (total) \|\| {{TV\|IP\|1.2}} per army (total)
			\|-
			\| [[Navy]] Maintenance \|\| {{TV\|IP\|0.5}} per navy \|\| {{TV\|IP\|0.4}} per navy
			\|-
			\| {{TV\|Unrest}} \|\| colspan=2 \| {{TV\|ip\|-1%}} for every {{TV\|unrest\|0.1}} above 2, capping at {{TV\|ip\|-80%}} at {{TV\|unrest\|10}}.
			\|-
			\| [[Councilor]] using [[Advise]] \|\| colspan=2 \| +1% per point of {{TV\|administration}} (but see below)
			\|}

			=== Multiple Advisors ===
			If a single nation gets the benefit of multiple councilors using the [[Advise]] mission, the benefits will decrease for every councilor after the first. The n-th advisor adds +(Advisor {{TV\|administration}} / n)% to IP.

			Assuming each advisor has 25 {{TV\|administration}}, the combined impact is:
			{\| class="wikitable"
			!\| '''# Advisors''' \|\| 1 \|\| 2 \|\| 3 \|\| 4 \|\| 5 \|\| 6
			\|-
			\| '''Total {{TV\|IP}} Impact''' \|\| +25.0% \|\| +37.5% \|\| +45.8% \|\| +52.1% \|\| +57.1% \|\| +61.3%
			\|}


			== GDP Per Region ==
			GDP is not truly tracked per [[region]] - a nation has a single GDPPC value, and when a nation acquires regions, the GDPPC values are averaged out (weighted by population). However, certain game mechanics do affect regional GDP, and for this purpose an effective regional GDP is used.

			When distributing GDP to regions within a country, the game distributes them based on region {{TV\|pop}} and economic modifiers. It pretends {{icon\|colony\|bgcolor=DarkSlateGray}}colony regions have 50% the people who actually live there, and that {{icon\|oil}}core oil, {{icon\|resource region}}core mining, and {{icon\|core economic region\|bgcolor=DarkSlateGray}}core economic regions have 125%, then distributes GDP evenly based on that modified population. This effectively means that regional GDP per capita is higher in core regions than in "regular" regions, and are lower in colonies.

			This affects the amount of {{TV\|mc}} capacity that can be built in each region, as well as determining the impact of events and projects that affect regional GDP.

			For example, suppose there is a nation with 60 billion GDP, composed out of 2 regions:
			* A {{icon\|core economic region\|bgcolor=DarkSlateGray}}core economic region with {{TV\|pop\|40 million}}.
			* A {{icon\|colony\|bgcolor=DarkSlateGray}}colony region with {{TV\|pop\|20 million}}.
			Then because of economic modifiers:
			* The {{icon\|core economic region\|bgcolor=DarkSlateGray}}core economic region with {{TV\|pop\|40 million}} is treated as if it has {{TV\|pop\|50 million}}
			* The {{icon\|colony\|bgcolor=DarkSlateGray}}colony region with {{TV\|pop\|20 million}} is treated as if it has {{TV\|pop\|10 million}}.
			So the 60 billion GDP is divided up such that:
			* The {{icon\|core economic region\|bgcolor=DarkSlateGray}}core economic region with {{TV\|pop\|40 million}} is given 50 billion GDP.
			* The {{icon\|colony\|bgcolor=DarkSlateGray}}colony region with {{TV\|pop\|20 million}} is given 10 billion GDP.
